Computing device operable to work in conjunction with a companion electronic device

ABSTRACT

A computing device is operable to work in conjunction with a companion electronic device. The computing device and the companion electronic device each have their own electronics and/or own operating system and each is able to construct a partial or complete user environment. The computing device is operable to send data to the companion device, on request of the companion device, which the companion electronic device then uses to locally construct its own user environment, in whole or in part.

BACKGROUND OF THE INVENTION

1. Field of the Invention

This invention relates to a computing device operable to work in conjunction with a companion electronic device. The computing device may be a mobile telephone or other kind of fixed or mobile device: the invention has the potential to revolutionize the way people use fixed or mobile devices, mobile phones and computers. The system and product embodiments plug the gap which has not been filled by smartphones, netbooks or smartbooks or other PDA style devices, and other consumer electronic devices, by bringing computer and media connectivity to mobile device users throughout the world, including in emerging markets which are looking to save on the cost of devices and infrastructure development.

2. Technical Background

In this invention, the computing device and the companion electronic device each have their own electronics and/or own operating system and each is able to construct a partial or complete ‘user environment’. A ‘user environment’ is the complete set of software and hardware components that together provide for output to and input from a user, where a user is a person, persons or another device (for example, for machine to machine (M2M) applications).

3. Description of the Prior Art

Four factors have been cited as the key drivers for the growth in smartphone computing devices in the coming years:—

-   -   Disruptive innovations in mobile software and hardware;     -   Rising consumer/business demand for mobile data (and         applications);     -   Faster wireless networks; and     -   Mass market smartphone and data pricing

Although both smartphones and notebooks markets and other computing and consumer electronic devices have benefitted from many breakthrough products in recent years, no device has yet been capable of providing a single solution that spans all user scenarios in a flexible and cost effective way. See Market Drivers, FIGS. 1 and 2.

Until recently mobile data consumption has been enabled mainly through two types of device, both predominantly the preserve of business customers:

-   -   Smartphones (<4-5″ display); &     -   Notebooks (>=13.0″ display)

However, as consumer demand for data services and downloadable mobile applications has increased, a host of alternatives devices have emerged as manufacturers and service providers seek to define the “ideal” consumption and creation device and their share of the associated revenues. Emerging mobile data category devices now include:

-   -   Netbooks (10.0″ to 13.0″)     -   Smartbooks (4.0-5.0″ to 10″)     -   Tablets (7.0″ to 10.0″)

But still there is a gap. The PC can use the bandwidth provided by mobile broadband networks but does not have the portability, where as a mobile phone has the portability but has a limited user environment and this limits the functionality and the ability to use the bandwidth that is available. Apple's iPad and other tablets try to solve some of these issues but have many limitations:

-   -   Still a two autonomous device solution . . . it's not a phone.     -   Modest display size (e.g., 9.7″)     -   Reliant on virtual keypad or (keyboard as an accessory)     -   Expensive     -   No Flash support on Apple devices (though browsing is supposed         to be a key benefit)     -   No printing

SUMMARY OF THE INVENTION

The invention is a computing device operable to work in conjunction with a companion electronic device, in which the computing device and the companion electronic device each have their own electronics and/or own operating system and each is able to construct a partial or complete user environment;

-   -   in which the computing device is operable to send data to the         companion device, on request of the companion device, which the         companion electronic device then uses to locally construct its         own user environment, in whole or in part.

This approach enables the companion electronic device to leverage off the computational resources of the computing device. In one implementation, the computing device is a smartphone and the companion electronic device has the form factor of a clamshell laptop or netbook; the smartphone provides the data that the companion device uses to locally construct its own user environment, in whole or in part. The smartphone need have no understanding of the configuration (e.g. display size) of the companion device and hence the data it sends is may be ‘generic’ data that is not specific to one type or model of companion device but instead can be used by a broad range of different companion devices.

By distributing the computational load in this manner across both the mobile device and the companion device, enables a combined system that is flexible, powerful and also efficient.

An implementation of the invention is called the PPC—the ‘Phone Powered Computer’. The invention can be implemented in a very broad range of forms.

DETAILED DESCRIPTION The Phone Powered Computer (PPC)

A PPC is a highly differentiated proposition that offers an innovative solution to emerging hardware, software and service models in relation to current and future network rollouts, emerging high-bandwidth value-added services, constantly shifting user-scenarios and existing and future business models such as cloud computing.

Essentially, a PPC system leverages the computing and communication capability of a smartphone (or other mobile or fixed electronic device) along with its applications, data, user interface elements, media, content, etc., making these available in form factors and/or use case scenarios that are more convenient, more optimized, or simply provide an alternative to using the smartphone (or other device) directly. This is achieved through a physical and or logical and or wireless connection to another device or devices that may resemble (but may not necessarily be) a familiar device category, such as a desktop, notebook or tablet computer. These other device or devices can have varied amounts of processing, storage, applications, user interaction, user feedback, input/output and data capabilities of their own, but may be less capable, less expensive and less complex than the familiar device type that they resemble.

Through its innovative multi-part architecture, a PPC may combine (as an example) a 3.5″ display smartphone with an innovative 11.1″ netbook computer (or a device that looks like one) to deliver a series of benefits that are both consumer wise and commercially very attractive.

Other examples of phone-powered computing include a phone or other electronic device referred to in this document as a Computing Device, connected wired or wirelessly directly or indirectly to a Companion device, also referred to throughout this document as a Companion Electronic Device, either or both of which may be, or may in turn be connected to:

-   -   Secondary display (s)     -   Peripherals such as memory, printer, etc.     -   Tablet (s) and devices with the appearance of a tablet.     -   Automobile or other transport displays     -   Computer (s) and devices with the appearance of a computer     -   Server (s)     -   Another phone (s)     -   Gaming console (s)     -   Keyboard (s)     -   Remote control (s)     -   Game controllers     -   Kiosk (s)     -   Portable navigation device (s)     -   Television (s)     -   Multimedia receiver (s)     -   Other multimedia systems     -   Point of sale device (s)     -   A docking stand     -   Industrial PDA's (e.g., warehouse or shop floor management)

The above are also examples of Companion Electronic Devices.

Although the concept is referred to as phone-powered computing, the mobile device need not be a phone. It could be any mobile (or fixed) device, also referred to through this document as Computing Device, including but not limited to:

-   -   Feature phone     -   Smartphone     -   Satellite navigation device     -   PDA     -   Media player     -   Camera     -   eReader     -   Tablet     -   Netbook/smartbook

PPC Benefits

Using fast, power efficient, processing, media and communications electronics, a PPC system creates a solution that delivers:

-   -   Low cost/high margin computing     -   Genuine breakthrough quad-play hardware and User environment         (UE) solution

For the purposes of this disclosure, “user environment” (UE) refers to the complete set of software and hardware components that together provide for output to and input from a user. A user may be a person or persons or another machine. These components may provide for any or all of the following, in whole or in part, and may also provide for additional means of output to or input from a user: Display screen, graphical user interface, textual user interface, motion user interface, audio user interface, camera, other optical sensor, LED or other light output, IRDA transceiver, proximity sensor, audio output, speaker(s), microphone(s), vibrator, haptics, touchscreen, buttons, keypad, trackpad, mouse, trackball, accelerometer, e-compass, other position/movement sensors, NFC transceiver, gesture capture mechanisms. In some cases, user environment may specifically refer to a subset of the above, for example, the graphical user interface and audio output.

-   -   Flexible mobile and notebook/tablet/television (or other form         factor) usability with an appropriate UE, for example:     -   Same (or varied) set of applications, data, Graphical User         Interface (GUI) elements, etc., in order to enable an         appropriate user experience for the Companion Electronic Device;     -   Consistency of user and application data (files, bookmarks,         history, preferences, etc.) across the Computing Device and         Companion Electronic Device     -   Appropriate state persistency across the Computing Device and         the Companion Electronic Device, such as maintaining browsing         session, open applications, application state etc. when         connecting, operating or disconnecting the Computing Device from         the Companion Electronic Device.     -   Common state and data consistency of Companion Electronic Device         applications by, for example, storing such information on the         Computing Device. A benefit of this would be to maintain the         same state and data set across a number of different Companion         Electronic Devices that the Computing Device could be connected         to at different times.     -   Ultimate productivity solution with class-leading power (in         terms of both processing power, i.e., capability, and power         consumption) efficiency.         -   See also related discussions of power (processing and             electrical) elsewhere in this document.     -   Multi-modal product architecture         -   See also related discussion of modes, multi-modal states,             system architectures and device architectures elsewhere in             this document.

The PPC concept will exert a disruptive influence compared to conventional wireless-device business models to deliver increased value at lower costs throughout the value chain.

For example, the Companion Electronic Device leverages the WAN connection (e.g. cellular) and subscription associated with the handheld device, saving cost for the cellular network operator in maintenance of multiple SIM cards and subscriptions and for the user in the cost of those multiple subscriptions.

PPC could reduce network operator subsidization cost because the BOM costs and hence selling price of the Computing Device and/or Companion Electronic Device are lower than standalone device and multiple subscription costs (“Two lower performance processors [Computing Device/Companion Electronic Device] are cheaper than one higher performance processor.”)

Multipart Architecture & the PPC Enabler

A PPC has two or more key parts, a Computing Device (‘C1’) and a Companion Electronic Device (or ‘C2’ . . . ‘Cn’), with the ability to plug-in and add other units, devices, tokens and similar.

A key characteristic of the multipart architecture is a “PPC enabler”. The PPC enabler is the collection of hardware and software components that allow the mobile device Computing Device user experience (or a modified version thereof), applications, data, connectivity, etc., to be displayed, accessed and/or controlled using elements of a second device Companion Electronic Device, or vice versa. Components of the PPC enabler may be distributed across the Computing Device, the Companion Electronic Device (s), or another element or elements as part of a physical or logical system between the Computing Device and the Companion Electronic Device.

-   See also later discussion of the PPC Enabler.

Key functions of the PPC enabler include:

-   -   Management of some or all video, audio, data, (user and system)         applications, control and UE signals to the single or a series         of integrated and or external wired, wireless, or networked         connection between Computing Device and Companion Electronic         Devices.     -   Optimisation and modification/reconfiguration of the UE when         connected or before or after a connection to an external device,         which could include, for example, a display of an alternative         format or resolution.     -   The interrogation, sensing and potential determination of the         system environment and the adaptation of the hardware, hardware         signals and software (RTOS, OS, applications and data) including         the presentation of the user environment in an appropriate         manner for the particular device and scenario.

In addition to encompassing many potential physical form factors and usage methods, there are many potential underlying, multipart hardware and software architectures which could form a PPC system.

These architectures may be described in two categories:

1. Hardware and Operating System Configurations (Some examples are shown in FIGS. 18 to 19.) 2. Software Configurations (Some examples are shown in FIGS. 20 to 24.)

Hardware and Operating System Configuration options include the placement of different hardware, operating system and enabler components variously in Computing Device, Companion Electronic Device or in other devices in the system. Relevant components may include but are not limited to:

-   -   Single or multicore general purpose processors, such as ARM,         MIPS, or X86-based processors     -   Application-specific processors or hardware components, such as         video or audio codecs     -   Any number of RTOS or OS instances, which may be instances of         the same or of different OSes, such as Android, iOS, Blackberry         OS, webOS, any Linux distribution, Windows, OS X, Neutrino,         Nucleus, OSE, QNX, etc.     -   Dedicated or shared OS kernels     -   Dedicated or shared memory     -   Hardware or software virtualization methods, such as OKL4,         Codezero, other hypervisors, Intel VT, etc.     -   Mechanical, electromechanical and physical or logical         interconnect components

Software configuration options relate mainly to distribution of various software tasks, such as UE element generation, application execution and data storage/access, around the system. Relevant components may include but are not limited to:

-   -   “PPC enabler” software components (See “PPC enabler” elsewhere.)     -   GUI or other UE element description     -   GUI or other UE element generation     -   GUI or other UE element adaptation     -   GUI or other UE element combination     -   GUI or other UE rendering     -   Input/output drivers and handing     -   User data     -   System data     -   Device Data     -   Preferences and settings     -   Applications     -   Application execution     -   Application results handing and output

Example Embodiments

There are many possible embodiments of Phone Powered Computing, both for the externally visible form factors/use scenarios of the devices/systems and for the underlying architecture of those devices/systems. These embodiments can divide into three complementary areas:

1. Form factor and use scenario 2. System architecture 3. PPC enabler

Potentially, any embodiment within each of the three complimentary areas could be used with any embodiment of the architectures or systems in any combination.

Form Factor and Use Scenario Embodiments

Many different form factors and use scenario embodiments are possible with the PPC concept some examples but not limited to are

-   -   Laptop-style Companion Electronic Device connected wired or         wirelessly to Computing Device     -   Tablet-style Companion Electronic Device connected wired or         wirelessly to Computing Device     -   Desktop-style Companion Electronic Device connected wired or         wirelessly to Computing Device with or without wireless         keyboard, trackpad remote control, and/or mouse.     -   TV dock-style Companion Electronic Device connected wired or         wirelessly to Computing Device, with or without wireless         keyboard, remote control, trackpad and/or mouse     -   TV dock-style Companion Electronic Device connected wired or         wirelessly to Computing Device, with the Computing Device acting         as the game controller or alternatively with wired or wireless         game controllers

Wired and wireless connections between Computing Device and Companion Electronic Device, or single to multiple Computing Device and Companion Electronic Device configurations are possible.

These example embodiments include many novel mechanical, electromechanical and software elements, and which may be wired or wireless, for example:

-   -   “PhoneTube”—A Companion Electronic Device dock for the Computing         Device that connects to a larger display such as a monitor or         television and may also connect to (or include) input/output         peripherals (either directly or through the computing device)         such as a keyboard, trackpad, mouse, camera, memory key,         speakers, printer, remote control, game controller(s), a cooling         system to cool the computing device and or the PhoneTube itself         to enable more performance to be obtained from the computing         device, etc. The device may also have wired or wireless         communication capability. Example use scenarios are analogous to         a desktop computer, a home media center/set-top box and a home         game console The computing device may physically connect to         PhoneTube thru an adapter means such as a “L” or “U” adapter         (providing side and end on interconnection) or other means         providing a consistent physical and electronic interconnection         to the PhoneTube independent of the computing device, thereby         avoiding the need for PhoneTube docks to be designed to         physically “fit with” or interconnect with each and every         computing device; see FIG. 26. The FIGS. 35, 39, 68, 70, 72 and         75-79 show various embodiments of a PhoneTube configuration.     -   “PhonePad”—A tablet style Companion Electronic Device to which a         computing device connects that may have any number of built-in         or peripheral functionalities and inputs/outputs (either         directly or through the computing device) such as a keyboard,         touchscreen, trackpad, mouse, camera, memory key, speakers,         printer, remote control, game controller(s), etc. The device may         also contain sensors such as accelerometers, e-compasses,         proximity sensors, light sensors, a cooling system to cool the         computing device and or the PhonePad to enable more performance         to be obtained from the computing device, etc. The device may         also have wired or wireless communication capability. Example         use scenarios are analogous to a tablet or convertible computer.         The computing device may physically connect to PhonePad thru an         adapter means such as a horse shoe or cassette style adapter or         other means providing a consistent physical and electronic         interconnection to the PhonePad independent of the computing         device, thereby avoiding the need for PhonePads to be designed         to physically “fit with” or interconnect with each and every         computing device. See FIG. 27. The FIGS. 16, 32, 41, 45-49, 64,         65, 67, 71 and 74 show various embodiments of a PhonePad         configuration.     -   “PhoneBook”—A notebook-style companion electronic device to         which a computing device connects that may have any number of         built-in or peripheral functionalities and inputs/outputs         (either directly or through the computing device) such as a         keyboard, display, touchscreen, trackpad, mouse, camera, memory         key, speakers, printer, remote control, game controller(s), etc.         The device may also contain sensors such as accelerometers,         e-compasses, proximity sensors, light sensors, etc, a cooling         system to cool the computing device and or the PhoneBook to         enable more performance to be obtained from the computing         device, etc The device may also have wired or wireless         communication capability. Example use scenarios are analogous to         netbook or notebook computer. The computing device may         physically connect to PhoneBook thru an adapter means such as a         horse shoe or cassette style adapter or other means providing a         consistent physical and electronic interconnection to the         PhoneBook independent of the computing device, thereby avoiding         the need for PhoneBook to be designed to physically “fit with”         or interconnect with each and every computing device. See         FIG. 28. The FIGS. 8-11, 14, 15, 30, 31, 33, 34, 42-44, 50-56,         60, and 69 show various embodiments of a PhonePad configuration.     -   “PhoneWrap”—A sleeve, “shoe” or dongle that attaches to a phone         or other computing device in order to supplement its capability         and to better enable PPC functionality. Example functionalities         of PhoneWrap could include the inclusion of additional         batteries/charging, video/audio conversion and/or compression,         video/audio transmission, data transmission, wired or wireless         communication, additional memory, and/or auxiliary processing         capability, the ability to cool the computing device to enable         more performance to be obtained from it, the addition of further         connectors in addition to or in replacement of the computing         devices. PhoneWrap can act as a physical and electronic adapter         for the physical and or wireless/network connection between the         computing device and the companion electronic device. Allowing         common PhoneTube, PhonePad, PhoneBook and other embodiments of         the PPC enabler to be created. With the adaptation for different         models of computing devices being dealt with different versions         of PhoneWrap. This has the benefit that if a user changes their         computing device they only have to change the PhoneWrap and not         all the other devices such as PhonePad. Similarly it allows as         single computing device to be used with multiple companion         electronic devices. In one embodiment PhoneWrap might be         integrated with a cover on the computing device allowing for a         more integrated and smaller combination of the computing device         and the phone wrap. See FIGS. 35-37.

Examples of alternative embodiments are also shown in FIGS. 57-59, 61-63 and 66.

-   -   1] A embodiment of PhoneBook is detailed with reference to FIG.         30—PhoneBook comprises a computing device 100 and a notebook         style companion electronic device 200 that are connectable to         each other and form an enhanced computing companion electronic         device. This combination of functionality is a phone powered         computer, with modular capability, and the ability to transfer         itself into different type of compatible products to suit the         user's scenario.     -   2] PhoneBook has two key parts, a computing device 100 and a         notebook like companion electronic device 200 with the ability         to host the computing device 100 and additionally to plug-in and         add other units, companion electronic devices, tokens and         similar. The companion electronic device 200 may accommodate the         computing device 100 via a horseshoe adapter between the docking         area 202 and corresponding section 102 of the computing device         100. The docking area 202 may be located next to the keyboard         203 where a regular notebook computing device known in the art         would feature a trackpad. In this arrangement, the touch screen         display 101 of the attached computing device might also function         as a trackpad. Other means might be used attach computing device         100 to companion electronic device 200. The multi-modal         opportunities of the computing device 100 and companion         electronic device 200 enable a series of different architectures         and functionality. The computing device 100 could work as a         remote pointing device. The computing device 100 can be a         projector or can connect to a TV display. The companion         electronic device 200 can be used as a host for multiple         computing devices, at the same or different times which might be         particularly useful for families and small businesses and         schools. For small businesses and schools only a few companion         electronic devices 200 will be needed, so employees and students         just plug in at work/school, and take home their work to plug in         at their home companion electronic device 200.     -   3] A potential embodiment of a PhonePad system is illustrated on         FIG. 32 and comprises an alternative companion electronic device         300 similar to a tablet computer, accommodating a computing         device 100 alongside its main display 301. Alternatively,         computing device 100 can be inserted into or attached to the         back side or any suitable portion of the companion electronic         device 300 examples of which are shown in FIGS. 41 and 45-49.         Once connected, the companion electronic devices 100 and 300 may         or may not work together to form a computing system. The         companion electronic device 300 has its own processor and         operating system, thus various communications, entertainment,         and computing functions are implemented and controlled by the         computing device 100 and the companion electronic device 300.         The screen 301 of the companion electronic device 300 might be a         touchscreen, thus alleviating the need for a hardware keyboard.         The companion electronic device 300 might have an on-screen         keyboard on display 301 or might have voice recognition means,         or hand-writing recognition means to allow user input beyond the         input capabilities of the computing device 100. The companion         electronic device 300 may optionally comprise an extra battery,         loudspeakers, graphics processor, Wi-Fi receiver, a backup         memory, and various connectors (not shown). These optional         components may complement the functionality of the connected         computing device 100.     -   4] An alternative embodiment might comprise a companion         electronic device 400 supporting both notebook type and tablet         type configurations—effectively a combination of PhoneBook and         PhonePad and is illustrated on FIGS. 33 and 34. The docking area         402 might be identical to the docking area 202 of the first         embodiment, allowing a computing device 100 to be inserted         either directly or via a horseshoe accessory. The difference is         that the display 401 is connected to the chassis of companion         electronic device 400 using a special hinge mechanism 404         allowing the display to be rotated. When the lid of the notebook         style companion electronic device 400 is closed, display 401         covers the keyboard 403 like the lid of a regular notebook         companion electronic device, however, when the lid is closed in         a reversed position of the display 401, companion electronic         device 400 can be used in a similar manner as the tablet         companion electronic device 300 of the second embodiment. As a         variation of this companion electronic device 400, or the         companion electronic devices 200 and 300 according to previous         embodiments, the display 401 may have its own battery pack (not         shown) and may be wirelessly communicating with other parts of         the companion electronic device 400 (or 200 and 300) or directly         with computing device 100. The benefit of a wirelessly         communicating display 401 is that it can be freely rotated to         any direction and can be placed anywhere (within reception         range) independently from the computing device 100 or the         chassis of companion electronic device 400.     -   5] A potential embodiment of PhoneTube is illustrated on FIG. 35         and comprises a docking stand 500 connectable to a TV set 506         and a keyboard 503. The docking stand 500 is arranged to receive         a computing device 100, either directly or via suitable adapter         means, such as a bracket positioned between the computing device         100 and the docking area 502 of the docking stand 500. The         adapter means might comprise a cassette or a cover at least         partially surrounding the computing device 100, or any suitable         wired or wireless connection. The keyboard 503 might be a         wireless keyboard and might incorporate a trackpad for         convenient user interaction with the computing device 100 and         companion electronic device. When connected to a TV 506 or an         external display companion electronic device via wire 505 or         other means, the docking stand 500 is arranged to transmit         multimedia signals from the computing device 100 to the TV 506         and/or to/from any further companion electronic devices capable         of displaying, playing back, or processing audio and/or video         signals. The audio and video signals can be either analogue or         digital signals (or a data representations thereof), such as         HDMI, composite, stereo sound, surround sound signals (or a data         representations thereof), and might include additional data         channels for carrying control signals and other data between the         computing device 100 and any external companion electronic         devices. The docking stand 500 is arranged to provide connection         to other peripherals such as a computer mouse, a computer         display, a network adapter, antenna, local or remote data         storage means. The docking stand 500 might also provide the         capability to act as a USB hub for connecting digital cameras         and other devices     -   6] The docking stand 500 is connected to a power source (not         shown) and is configured to charge the inserted computing device         100. The docking stand 500 with the connected computing device         100 and the TV 506, or companion electronic device with the         optional keyboard and mouse, together form a phone powered         computing system, providing enhanced and complemented         functionality to the computing device 100.     -   7] PhoneTube is a computing and entertainment solution that         delivers PPC benefits to the users, enabling the computing         device to become a large-screen computing, browsing, email and         productivity solution unburdened by the limitations of a small         screen. PhoneTube provides a simple, cost-effective way to         connect computing devices to a TV or other large-format display         to convert non-internet enabled TV's and monitors to become         internet-enabled, and/or to connect computing devices to a         second display to enable enhanced operation and functionality.     -   8] PhoneTube is a software and hardware solution that provides a         way of utilising inherent computing device, and companion         electronic device processing power, user environment elements,         resident user-data and web-access for increased convenience with         minimal complexity. Because computing device elements are scaled         and optimized on the companion electronic device.     -   9] PhoneTube enables users to use functions of their computing         device and or companion electronic devices through the TV         interface. The functions may include but are not limited to:         -   Email and web browsing         -   Photo and movie viewing         -   Enhanced usability of resident general purpose productivity             software         -   Access to phone-based compute solutions and operator             services         -   Downloadable applications         -   Video conferencing         -   Music management and playback         -   Gaming     -   1] PhoneTube hardware may come in the form of a push-in/slide-in         desktop dock as described above that users simply place their         computing device into to enable connectivity between the         computing device and the companion electronic device. The         hardware could comprise, for example, the following items:         -   Base cradle         -   Connector and signal board that routes out signals from the             phone, through the dedicated mechanics and/or horseshoe             adapter to provide appropriate HDMI/USB signals.         -   Horseshoe adapter, where appropriate, that mates up with             phone-based I/O and combines them into one single wiring             harness that connects to PhoneTube's standard connector         -   USB connectors and other interface connectors.         -   3.5 mm audio connector         -   RCA phono connector         -   HDMI connector         -   Full sized QWERTY keyboard with integrated multi-touch             trackpad         -   Power supply         -   Optional TV clip-on attachment     -   1] The base cradle has system connectors to connect with         computing devices, either directly, or via a horseshoe adapter.         The base cradle functions as a hub for connecting the computing         device to an external display, such as a TV screen or other         displays, and also to connect a wireless keyboard to the         computing device so that the user can interact with the         computing device and or companion electronic device The wireless         keyboard might also comprise an integrated trackpad for more         convenient interaction.     -   2] The horseshoe adapter securely connects to the specific         input/output connectors of the computing device, and on the         other side, the adapter connects to the specific system         connectors of the PhoneTube cradle. The computing device         specific horseshoe adapters make it possible to use various         computing device models with the same cradle. Apart from         providing connectivity for different types of computing devices,         the horseshoe adapter also functions as a support means to hold         the computing device firmly in the cradle. The multimedia output         of the computing device is thus linked to the companion         electronic device and or the external display, while the power         supply of the PhoneTube charges the connected computing device         100.     -   3] Optionally, a TV clip-on attachment might be provided to         place the PhoneTube cradle (with the attached computing device)         in a desired position, for example, on the top or at the side of         the TV frame. Such arrangement might be practical in case the         user wants to use the video conferencing function. The clip-on         attachment, or the horseshoe adapter, or the cradle itself might         be tiltable to provide optimum viewing angle for the computing         devices camera so that it's always facing the user. The camera         might be on the back of the computing device since the user         doesn't have to see the computing devices display screen, as         applications are now displayed on the TV screen. Therefore,         computing devices with only a back-facing camera are now capable         to provide video conferencing functions. The other advantage is         that the camera on the back of the computing device usually has         a better resolution than the camera on the front. Therefore,         high quality video conferencing might be implemented using the         PhoneTube and the attached computing device.     -   4] PhoneTube enables a UE to be driven through the TV or a         companion electronic device.     -   5] In a potential embodiment of PhoneWrap, the horseshoe adapter         is replaced with a cover 600 for the computing device 100, the         cover 600 substituting or alleviating some of the parts found in         the previous embodiments. As shown on FIGS. 36 and 37, the cover         600 might serve as an adapter between the companion electronic         device connectors 102 and the cradle's system connector 502, or         alternatively, the cover 600 might comprise a wireless         transceiver 607 to connect wirelessly to the PhoneTube cradle         500, which is also fitted with an appropriate wireless         transceiver. When connecting wirelessly, there is no need for a         regular cradle, into which the computing device 100 would be         inserted, thus the modified cradle can be implemented in a         simplified form. The PhoneWrap cover 600 might also contain         extra battery 608 to provide longer operation time for the         companion electronic device 100 and might also contain a cooling         system (not shown) to keep the computing device 100 cool         enabling additional computing resources to be activated in the         computing device 100 and the wireless transceiver 607. Charging         of the computing device 100 might be done using the computing         devices regular charger but alternatively, any companion         electronic device capable of receiving computing device 100 with         PhoneWrap cover 600 might be used to charge the computing device         100 and the extra battery 608. However, the PhoneWrap cover's         extra battery or the computing devices own battery might be used         to power an external accessory such as any of the companion         electronic devices 200, 300, 400, 500, in embodiments 1 to 6         respectively, thus alleviating the need for a battery in the         companion electronic devices 200, 300, 400, 500 or connecting         the companion electronic devices 200, 300, 400, 500 to a power         outlet. In a specific arrangement depicted on FIG. 37, the         PhoneWrap cover 600 might replace the back cover of computing         device 100, thus making it possible to remove the internal         battery of computing device 100 and use extra battery 608         instead. In this arrangement there is no need for two separate         batteries, thus the Phone Wrap cover 600 becomes a more integral         part of computing device 100. FIG. 36 also shows adapter means         612 to connect the computing devices ports 102 to the system         connectors of any PPC companion electronic device. An example of         the system connector 511 is shown in FIG. 39.     -   6] The PhoneWrap's wireless transceiver 607 and its base cradle         counterpart (not shown) functions primarily to connect the         computing device 100 wirelessly to the TV 506, or companion         electronic device Therefore, the base cradle 500 might be         substituted with a dongle connecting to the multimedia inputs of         the TV 506 or Companion Electronic Device An example wireless         protocol to implement this embodiment is WiFi. However, other         wireless transmission technologies might be used instead. The         phone cover 600 with wireless transceiver 607 can be permanently         left attached to the computing device 100, thus the user doesn't         have to attach the computing device to a cradle to begin using         the PPC system. The cover 600 will also provide added protection         to mechanical impacts or other environmental threats.     -   7] The computing device 100 might remain in the user's bag or         pocket as long as the PhoneWrap cover 600 is on the computing         device and the computing device is within range of the PhoneTube         cradle 500 or dongle. An accessory wireless keyboard might be         used to trigger the connection between the computing device 100         and the companion electronic device 506. Alternatively, the         connection might be initiated automatically, by the companion         electronic device once the computing device 100 is within range         of the companion electronic device 506 or upon user interaction         with the computing device 100 or the companion electronic device         506.

Adapter Means

-   -   8] Potential adapter means for use with various embodiments of         the PPC systems will be described with reference to FIGS. 38, 39         and 40, using the docking companion electronic device 500 as an         example. The same or similar adapter means might be used in         conjunction with any of the companion electronic devices 200,         300, and 400 of other embodiments.     -   9] Since computing device 100 might have its own specific         connectors 102 and interfaces, adapter means might need to be         used to provide a suitable mechanical and electrical connection         to the system connector 511 located in the docking area 502 of         docking stand 500, or corresponding docking areas 202, 302, 402         of other embodiments. Different kinds of computing devices have         different connector layouts, and in some cases, connectors might         be located on more than one side of computing devices 100. An         L-shaped bracket 512 might be used to connect along its internal         edges to the appropriate computing device connectors 102 along         the outer edges of the computing device 100. The L-shaped         bracket 512 is connected to computing device 100 as shown by the         arrow on FIG. 38.     -   10] As indicated on FIG. 39, L-shaped bracket 512 slides into         docking stand 500 in the direction of arrow A or arrow B and         connects to the docking station's system connector 511 along its         outer edges, either on the sides or along the bottom, or any         suitable area. computing device 100 might be attached either         before or after connecting bracket 512 to docking stand 500. The         L-shaped bracket might have computing device specific connectors         along one edge, or both edges. Bracket 512 might have different         types of connectors along its edges, making it possible to adapt         different kinds of computing devices to docking stand 500.         Multiple connectors on bracket 512 might also allow insertion of         computing device 100 in various orientations, such as landscape         and portrait orientations.     -   11] However, bracket 512 might be implemented in different         shapes, such as a bar-shape, U-shape, or in the form of a         rectangular bracket, enclosing computing device 100 along 1, 3,         or 4 sides respectively. It is not beyond the scope of the         invention to provide a bracket that is similar to cover 600 of         embodiment 4, fully enclosing the computing device 100 from at         least 5 sides. It is seen that an L-shape provides optimal         connection to many computing device types with different         connector layouts while also providing adequate support to hold         computing device 100 in docking area 502.     -   12] In one embodiment, depicted on FIG. 40, bracket 512 is         replaced with a cassette 513. computing device 100 slides into         cassette 513 in the direction indicated by arrow C. Optionally,         cassette 513 might have a counter-part 514 that can be connected         to cassette 513 or to computing device 100 as indicated by         arrow D. Cassette 513 and counter-part 514 might be implemented         as a single element, and might also be implemented as part of         the chassis of either of companion electronic devices 200, 300,         400. Bracket 512 might be used as counter-part 514. The cassette         513 might be implemented with fixed outer dimensions that make         it possible to attach any inserted computing device to any of         docking areas 202, 302, 402, 502, while also providing a rigid         construction when used in conjunction with companion electronic         devices 200, 300, 400, or 500.

Further Embodiments of the PPC System

-   -   13] FIGS. 41-55 illustrate further alternatives for connecting a         computing device 100 with companion electronic device 200 or 300         to arrive at a PPC system according to the invention. The         computing device might be simply connected to companion         electronic device 200 by wire 105 as shown on FIGS. 41 and 42.         In this case, docking area 202 might be formed by a strip of         leather or textile, or it might be in the form of a pouch as on         FIG. 43. The computing device 100 might be attached to the back         of display 201. However, when using wire 105, docking area 202         is optional or it might comprise an USB port or similar, and the         computing device 100 might be placed simply on the desk next to         companion electronic device 200. The docking area 202 might also         be part of the hinge 204 that connects the two main parts of         companion electronic device 200, as depicted on FIG. 44.     -   14] The computing device might be inserted and fully enclosed         into the companion electronic device as shown on FIGS. 45 to 49.         The Computing device might be placed behind a flap panel         covering the docking area 302 (FIG. 45), or might be connected         via a slide-in element shown on FIGS. 46, 47 and 48. FIG. 47         also depicts a cartridge 315 that might accommodate the         computing device and, if necessary, any adapter means or         alternatively, the cartridge 315 might contain a wireless module         for communication with a mobile phone in the vicinity of device         300. Display 301, front and rear chassis and bezel of device 300         can be re-used for both docked and wireless configuration. The         rear of device 300 has a configurable central element that will         fit cartridge 315 containing either the computing device or the         wireless module.     -   15] In an alternative arrangement shown on FIGS. 48 and 49, the         docking area 302 might be located at the edge of the chassis of         device 300, and might provide means to attach the computing         device to the companion electronic device 300 via a rotatable         connector that allows using the computing device 100 either         alongside the display 301 (FIG. 49—front view) or flipped into         the back side of the chassis of the companion electronic device         300 (FIG. 49—rear view).     -   16] FIG. 50 illustrates a modified companion electronic device         200 with its docking area 202 located between keyboard 203 and         display 201. On FIG. 8 l, the docking area 202 also allows using         the computing device 100 alongside display 201. The docking area         202 might be part of the keyboard 203 as shown on FIG. 8 m. The         two parts of keyboard 203 can be pulled apart to accommodate         computing devices of various sizes. As shown on FIGS. 53 and 54,         the display 201 might be raised so that the docking area 202,         between the keyboard 203 and the display 201, can also         accommodate computing devices of various sizes.     -   17] FIGS. 55 and 56 depict yet another solution, wherein the         computing devices 100 is connected to a docking area 202 formed         in the frame of display 201. Any further docking areas might be         implemented without departing from the scope of the invention.         Connection between the computing device 100 and any of the         companion electronic devices 200, 300, 400, 500, 600 might be         achieved with or without a docking area, either directly, or         using adapters, wires, or wireless means.     -   18] A variation on several of the above embodiments may utilize         a cable connection between the Computing Device and the         Companion Electronic Device. The cable may be fixed to or         removable from either device and may be retractable.

“Smart Computing Device/Smart Companion Electronic Device” Characteristics

Potential characteristics of the “Smart Computing Device/Smart Companion Electronic Device” embodiment include:

-   -   1. Relying on the Computing Device connected directly or         indirectly to a companion electronic device to run at least some         applications,     -   2. Relying on the Computing Device connected directly or         indirectly to a companion electronic device to create at least         some intermediate UE elements that will be eventually be         incorporated by the Companion Electronic Device into its own UE     -   For the purposes of this disclosure, “UE elements” may refer to         graphics assets, GUI gadgets or widgets, display images, partial         display images, input/output control methods, audio, commands,         haptic or other feedback method instructions, application         results, application content (e.g., web page, phonebook entry,         etc.), or any other component or part of a component of the user         environment, or a description or tokenization thereof.     -   3. Relying on services or other methods/capabilities present in         the Computing Device connected directly or indirectly to a         companion electronic device such as OS and/or hardware/and or         applications to help prepare intermediate elements (e.g. display         image, data or audio streams) that are independent of the         configuration of the Companion Electronic Device that may then         be incorporated into the Companion Electronic Device's UE, with         or without modification.     -   For the purposes of this disclosure, “services” may include         those such as formatting graphical elements for a particular         resolution, density and/or orientation as required by the         companion device; Employing techniques to take advantage of         larger screen real estate which may be available, such as         preparing to display more information than would otherwise be         possible on relatively smaller screen real estate; or the same         information with more fidelity (e.g. higher resolution, colour         depth, etc); one or two way communications or networking; input         or output; electrical power; processing power; application         execution, etc.     -   3.1. The Computing Device services' actions may require         information to be shared between the Computing Device and         Companion Electronic Device, and could include:     -   3.1.1. Instructions from the Companion Electronic Device to         Computing Device to behave in certain ways in order to assist         the Companion Electronic Device in providing its separate user         environment     -   3.1.2. Using input and output peripherals and or elements of the         Companion Electronic Device in place of or in parallel to the         Computing Device's own and vice versa     -   3.1.3. Rendering display graphics for a particular screen         resolution, density or orientation     -   3.1.4. Using network connection elements of the Companion         Electronic Device in place in parallel or in a multiplexed way         to the Computing Device's own, or vice versa     -   3.1.5. Creating an intermediate user environment, that could         include GUI, input/output elements, etc.     -   4. Companion Electronic Device inserting the Computing Device         display image (or not) or elements thereof, which is built from         elements provided by the computing device which could be a         window within the Companion Electronic Device UE or could be         more.     -   5. Modifying (stretching/rendering/etc.) (or not) the Computing         Device screen image display or a part or element of to be sized         and adapted appropriately for the Companion Electronic Device         display configuration, Processing and intelligence for this         occurs on the Companion Electronic Device, and the Companion         electronic device instructs the computing device to provide         elements that can be incorporated into the companion electronic         device UE.     -   6. At certain times combining elements of the intermediate         environment from the Computing Device with locally generated         elements on the Companion Electronic Device; Processing and         intelligence for this combination step occurs on the Companion         Electronic Device.     -   See example UE generation flow in FIG. 3.     -   7. Following this adaptation step, displaying the combination of         the Computing Device UE and the Companion Electronic Device UE         on a display connected to physically, wirelessly or over a         network or incorporated in the Companion Electronic Device; In         parallel outputting audio and/or other associated feedback, such         as audio or haptic feedback, from Companion Electronic Device         that may have originated on either Computing Device or Companion         Electronic Device.     -   8. An embodiment could include peripheral, input device, output         device, etc. handling and/or notification by the Companion         Electronic Device to the Computing Device, with the benefit of         abstracting these additional elements from combinations of the         Computing Device hardware, software and/or UI.     -   9. An embodiment of this invention could be to send tokens         representing elements of the Computing Device environment, i.e.,         abstracting those elements, rather than sending the elements         themselves, reducing processing power, bandwidth and other         system requirements of the two devices, which are then used to         generate those elements on the Companion Electronic Device.         Tokens may be novel or may use industry standard or de facto         standard methods such as XML, Flash, etc.     -   9.1. The Companion Electronic Device could use those tokenized         elements in whole or in part within its own UE     -   9.1.1. An embodiment could be for the Companion Electronic         Device to query the list of applications available (possibly as         tokens) on the Computing Device which are then used by the         Companion Electronic Device to build an application selection         screen within its own UI. The Companion Electronic Device's         application selection screen could combine applications residing         on Computing Device and Companion Electronic Device and run on         either the Computing Device or the Companion Electronic Device.     -   10. Because the Companion Electronic Device environment is         generated locally, certain interactions with or actions of the         Companion Electronic Device may not require continuous         interaction with the Computing Device or use of Computing Device         resources, helping to conserve Computing Device resources         (processing, power consumption, etc.) and reduce interface         bandwidth and power requirements     -   10.1. An embodiment of this characteristic could be to transmit         a lower resolution video stream from the Computing Device to the         Companion Electronic Device which is then upscaled on the         Companion Electronic Device for output on a larger display, thus         reducing the processing requirement on the Computing Device and,         by extension, the power consumption of the Computing Device, and         by extension the interface bandwidth requirements and interface         power consumption.     -   10.2. A further embodiment of this characteristic would enable         the Computing Device to switch off or put into sleep mode         certain Computing Device resources that are not required in a         linked state when the Companion Electronic Device has its own         processing and I/O resources. For example, the Computing Device         might switch off or put into sleep: Display, display driver,         audio drivers, portions of memory, other system elements, etc.     -   10.3. A further embodiment of this characteristic could be batch         transfer of data from the Computing Device to the Companion         Electronic Device (e.g., songs in a playlist) to eliminate the         need to continually transfer data     -   11. Because the Companion Electronic Device environment is         generated locally, the Computing Device's own environment may or         may not be used independently of the Companion Electronic         Device's environment, e.g., to answer a call.     -   12. Because resources on the Computing Device are employed less         than they might be in models where the Computing Device takes         responsibility for generating the Companion Electronic Device         user environment, it is more likely that multiple Companion         Electronic Devices could be used simultaneously with the         Computing Device, for example in different rooms of a house.         Variations of this could allow for simultaneous use of the same         Computing Device applications on different Companion Electronic         Devices or alternatively restricting certain applications or         portions thereof from different companion electronic devices.         This could also enable application developers to create         applications which have multi-user use cases.     -   12.1. An embodiment could include the Companion Electronic         Device receiving bitmap (or other) representations of the         display from the Computing Device with a software program on the         Companion Electronic Device that analyses those bitmap         representations with the intent of adapting the content to         display more appropriately on the display of the Companion         Electronic Device. For example, soft buttons, text or other UE         elements and controls could be differently laid out over the         different area available on the Companion Electronic Device         display. A further embodiment could instead receive, similarly         analyse, and re-purpose non-bitmap image or video data such as         SVG- or Flash-based data.     -   12.1.1. Another possible embodiment is to have Computing Device         UE library calls routed to Companion Electronic Device which         implements the rendering and could possibly adapt the intended         layout to different display configurations.     -   12.2. Another benefit is greater potential for the Computing         Device to work with multiple Companion Electronic Devices,         because the Computing Device does not have to generate the user         environment for the Companion Electronic Device.     -   13. The OS and other software for the Companion Electronic         Device may be loaded from the Computing Device initially and/or         periodically (or not); Benefits of this approach include:     -   13.1. The Companion Electronic Device could more easily be         enabled to work with multiple types of computing devices,         including with different OSes.     -   13.2. The Companion Electronic Device is more “generic”, with at         least some of the Companion Electronic Device software designed         to match the capability of the specific computing device         software.     -   13.3. The Companion Electronic Device software can be updated         periodically via the Computing Device without requiring         independent data connectivity on the Companion Electronic Device     -   14. The Computing Device's data and/or applications may or may         not be copied to and synchronized continuously between the         Computing Device and the Companion Electronic Device reducing         the amount of data that is moved around within the system.     -   14.1. An embodiment of this idea could allow for applications to         be run locally on the Companion Electronic Device     -   14.2. An embodiment of this idea could synchronize via a local         or remote server rather than directly between the two devices

The novel step in many of these embodiments is a significant reduction amount of the data and the number of times it is moved around the system.

New Technology Features

The PPC concept pioneers many new technology features. Some of these features may apply to one or a number of the possible form factor/use scenario, architecture and PPC enabler combinations, while others may be applicable all possible combinations.

Context Scaling

The concept allows and enables context scaling, in particular but not necessarily exclusively, a “Smart Computing Device/Smart Companion Electronic Device” embodiment could include:

1. Display scaling 1.1. Because the Companion Electronic Device is responsible for generating the user environment, the Computing Device need not be aware of user environment characteristics, such as the resolution of the Companion Electronic Device display. The Companion Electronic Device scales, aggregates and otherwise combines resources from the Computing Device and/or the Companion Electronic Device or just the Companion Electronic Device itself appropriately The Companion Electronic Device could do this for a range of Companion Electronic Devices and or each Companion Electronic Device could do this aggregation and combining independently. 1.2. The Companion Electronic Device could undertake appropriate display and display asset/element (such as UE graphics or video) scaling, if such mechanisms are not already present in the Computing Device OS, or in combination with such mechanisms in the Computing Device OS. 1.3. Elements provided by the Computing Device could be scaled to full or partial Companion Electronic Device screen sizes using mechanisms already present in the Computing Device OS. The Companion Electronic Device may instruct the Computing Device system to prepare UE elements for the alternative screen size, which could be the full size of the Companion Electronic Device display or a portion thereof. Android is an example of an OS that could run on Computing Device and be instructed to or “managed into” providing appropriately scaled elements by Companion Electronic Device. 1.4. Applications could be rebuilt/replaced to run in the Companion Electronic Device environment to leverage the larger display, using graphics, data and other assets present on the Computing Device. For example, the Computing Device's application launcher could be replaced as previously described in Section 6. An embodiment could be for the Companion Electronic Device to query the list of applications available (possibly as tokens) on the Computing Device which are then used by the Companion Electronic Device to build an application selection screen within its own UI. The Companion Electronic Device's application selection screen could combine applications residing on Computing Device and Companion Electronic Device and run on either the Computing Device or the Companion Electronic Device. 2. Application scaling, which could include: 2.1. Optimising the experience of the application to Companion Electronic Device environment e.g., Use of surround sound software speakers in the Companion Electronic Device or use of a trackpad interface 2.2. Additional feature availability (functionality scaling), such as adding printing capability when docked and or connected to a Companion Electronic Device 2.3. Full PC-style browser when connected, such as by changing user agent profile and UE. Another example would be to use Computing Device as a modem with local Companion Electronic Device browser 2.4. Enhanced application A/V experience such as 3D graphics and surround sound 2.5. Taking advantage of OS system capabilities which allow applications to use greater or lesser screen real estate, if it is available, such Android's Fragments or similar capability in other OSes. 2.6. In another example, applications (or the system on behalf of applications) could recommend to display or automatically display on the most appropriate screen if multiple screens or cameras that are available in the system, for example a smaller screen in a Computing Device and a larger screen in a Companion Electronic Device. For example: 2.6.1. Telephony applications could display on the smaller Computing Device screen whilst a word processor or browser could display on the larger Companion Electronic Device screen. 2.6.2. Video or movies could display on the larger Companion Electronic Device screen, perhaps with transport controls on the smaller Computing Device screen. 2.6.3. A camera on a computing device or on a companion electronic device to act in a modified way using different focus and or other settings when it is used in a specific mode such as video conference mode for example. 3. OS scaling, which could include: 3.1. Additional applications and/or new OS or capability (running locally on the Companion Electronic Device), for example: 3.1.1. Peripheral drivers, etc. 3.1.2. New applications 3.1.3. Power/thermal management 3.1.4. Optionally using an additional and perhaps more familiar OS such as a PC OS on the Companion Electronic Device.

Intelligent Status and Mode Management

The PPC concept includes a number of functionalities to intelligently or manually manage status and modes.

1. Preference settings 1.1. Computing Device and Companion Electronic Device could each be a master or a slave device—For example, one Computing Device could be a master to another Computing Device (which still being a slave to the Companion Electronic Device), acting as a game controller, for example. 1.2. The Companion Electronic Device can be a dumb device or a smart device. 1.3. The extra functionality can be a drop out box or a plug in device 1.3.1. Drop out box=PhoneWrap, for example, a portable dock that attaches to the mobile device which in turn connects wirelessly to a Companion Electronic Device or an add on module to the Companion Electronic Device. 1.3.2. Plug-in device=Computing Device docks into Companion Electronic Device or an intermediate device. 1.4. The settings on the Computing Device can tell the Companion Electronic Device what preferences the user wants and what mode they want to be in; or the settings on the Companion Electronic Device can tell the Computing Device what preferences the user wants and what mode they want to be in 1.4.1. Companion Electronic Device user preferences are stored on Computing Device so that user preferences can be consistent across multiple Companion Electronic Devices 1.4.2. Computing Device user preferences, for example Computing Device application settings are also stored on Computing Device 1.5. Also, the settings on the Computing Device can tell the Companion Electronic Device what preferences the user wants and what mode they want to be in. 1.6. Companion Electronic Device could automatically detect the Computing Device and ask if it wants to connect; Computing Device answers based on a user preference on Computing Device.

-   -   See example detection flows in FIGS. 4 and 5.

2. Switch off

2.1. The switch off devices can be a soft switch off or a hard switch off 2.2. Soft switch off can be turning down system elements, changing mode, etc. 2.3. The Computing Device can remember what the last user status was, and what the last preference settings were when the Computing Device user last logged in to the Companion Electronic Device, or vice-versa. 2.4. The Companion Electronic Device unit can have auto-switching between Computing Device mode and computer mode and headset mode (Bluetooth or wired headset)

3. Antennas

3.1. Computing Device and Companion Electronic Device could have independent antennas 3.2. Switch antennas based on mode between the Computing Device and Companion Electronic Device could have conductive or inductive coupling of Computing Device antennas to the Companion Electronic Device to improve radio/antenna performance of the Computing Device. 4. Telephony mode—Examples include: 4.1. Using the Computing Device user environment rather than the Companion Electronic Device environment to handle incoming and outgoing calls, e.g., displaying incoming call notifications and playing the ringer through a phone handset rather than the PhoneTube and television that it may be connected to. 4.2. Routing call audio through a Bluetooth or wired headset rather than through the audio input/output components of either the Computing Device or the Companion Electronic Device.

Intelligent Power & Processing Management

The PPC concept provides for many benefits of intelligent power and processing management.

1. Prioritizing the Charging Process

Traditional charging schemes for Computing Devices and laptops are very simple relating only to the charging of the battery in a single device from any external power source and the operation of that Computing Device when certain charge levels are met within the battery. The new scheme which describes the interaction between the two sets of batteries will require adaptations to the Computing Device charging software, which may be provided dynamically by the Companion Electronic Device on a case by case basis, additional icons on the Computing Device screen and the development of a “configuration” or “settings” application to allow the user to modify the charging behavior and limits.

Adding to the power and charging options of the Computing Device is one of the benefits of PPC. The additional set of batteries that can be contained in the Companion Electronic Device “dock” provides a benefit to the user even without the much broader use options that the dock affords.

There are five separate modes to consider:

-   -   Charging of batteries/use of external power in the Computing         Device when Computing Device is alone     -   Charging of batteries/use of external power when Companion         Electronic Device is alone     -   Charging of batteries when Computing Device is docked without         external power     -   Charging of batteries/use of external power when docked and         plugged into an external power source     -   Computing Device charges or powers Companion Electronic Device         -   In addition it is important that the amount of charge left             in the Computing Device and dock, when a device is being             charged and the source of that charge are all clear to the             user via the displays of the Computing Device and or the             Companion Electronic Device dock. This could be achieved by             way of example by using icons in the display of the             Computing Device and or Companion Electronic Device and             arrows to show the direction of charge.             1.1. Charging of batteries/use of external power in the             Computing Device when Computing Device is alone—This is             simple and will be determined by the Computing Device             manufacturer—there is no change required to current methods             used.             1.2. Charging of batteries/use of external power when dock             is alone.

The batteries will be charged whenever the external power is connected. This can be signaled to the user by the presentation of a simple display (e.g. A battery filling up) or if there is no display by way of example a colour changing LED which will show red when the battery is below a usable limit, for example flash when charging and become green when fully charged. When external power is connected the dock could be driven from this source to conserve the battery charge, excess charge current will be used to charge the Computing Device and Companion Electronic Device batteries if required.

1.3. If the battery is below its useful charge limit the whole dock should be operable from the PSU which should be capable of providing charge to the battery and simultaneously to power to the dock unit. 1.4. Charging of batteries when Computing Device is docked without external power

If the Computing Device battery is below a set limit x % and the dock batteries are above y % then the Computing Device battery will be recharged from the dock battery and the Computing Device will be operated from either its own battery or the Companion Electronic Device dock battery.

If the Computing Device battery is below a set limit m % and the Companion Electronic Device dock batteries are below n % then both could conserve their power for themselves. This assumes the batteries are running low and the user would want to keep the function of the dock Companion Electronic Device. This behavior can be changed by the user. By way of example, it can be overridden by the user in the “settings” application to allow “emergency” use of the dock battery to power the Computing Device.

These limits x, y, m and n should be configurable via software. The limits can be factory defined in the software prior to shipment or can be set up by the user.

The display of the Companion Electronic Device may show that the dock is charging the Computing Device as well as showing its own charge status—it may use of two different symbols for the two batteries to avoid confusion. The system may also use different warnings to indicate that low battery condition exists on either the Computing Device or Companion Electronic Device.

All indications related to charging and charge status of the Computing Device may be visible at all times on the Companion Electronic Device dock display as the Computing Device display may be turned off in some situations to conserve power or be used for another application (e.g. as a mouse).

1.5. Charging of batteries/use of external power when Computing Device is docked and dock is plugged into an external power source

When connected the external power may be used to provide power to the Companion Electronic Device dock and or the Computing Device and recharge all or some of the batteries of either device.

The display of either the Companion Electronic Device and or Computing Device shows which battery is charging as well as the charge status of the other battery—the system may use different symbols for the different batteries to avoid confusion.

If the Companion Electronic Device dock does not have a display it may have another indicator which indicates to the user that it is charging the Computing Device.

One method of controlling the charging schemes is the use of USB “on the go” with the dock and Computing Device able to interchange their master/slave identities within the scheme.

1.6. Computing Device charges/powers Companion Electronic Device In some cases, the user may wish for Computing Device to power or charge Companion Electronic Device, for example when external power is not available for Companion Electronic Device, and its batteries are very low or are depleted. In that case Companion Electronic Device could be powered and/or charged by the batteries or external power connected to Computing Device, based on user action or user preference settings.

1. Up Scaling and Downscaling

It is critical in any mobile solution to maximise the usage time between charges and to efficiently manage the power and thermal characteristics of the unit. The greater the usage time the greater the utility provided to the user. This element of the invention governs the way in which the processors (especially multicore units) in the Computing Device are controlled to maximise performance and reduce current drain and heating impact. This control covers but is not limited to, Computing device and companion electronic device system and processor and memory clock rates the number of cores active at any time and overall processor active periods, the variability of clock rate selection dependent on battery charge state as well as a deep sleep mode used in the computing device and or companion electronic device(s) when not connected to each other. The clock rates used will vary by mode as defined elsewhere in this document and may also depend on the intensity of CPU usage required. Prior art exists for the manipulation of clock rates within a PC or Computing Device as a single device. The novel part of the invention is that the clock rate used for a given state or for a given type of content e.g. web browsing or game play will vary based on the available power to the overall system specifically the case where a Computing Device unit or a Companion Electronic Device is wirelessly and or physically docked and connected to external power this may take the form of additional batteries and or power for another source such as mains power in a physically docked mode the Computing Device and Companion Electronic Device units will be able to increase/decrease the System voltage and or current (or an element of the system voltage, and or current e.g. processor or memory only) to in addition the system clock speed (processor, memory, bus, and internal/external interfaces), can be adjusted as can settings such as the display brightness, system element power states (e.g., audio electronics is switched off if no audio required), enabling/disabling I/O ports or internally buses etc enabling an optimum overall configuration of the Computing Device and Companion Electronic Device dependent on the application and the available power to the system. The effect of physically docking and or connecting wirelessly or otherwise the Computing Device or Companion Electronic Device may enable an enhanced active or passive thermal solution such as a fan or a heat sink to be enabled with the Computing Device and or Companion Electronic Device or in another device in one embodiment a cooling system on the companion electronic device could be used to cool a physically connected (docked) Computing device, Cooling systems will allow the Computing Device and or the Companion Electronic Devices to be kept cooler allowing System voltage and or current (or an element of the system, e.g., processor or memory only) to increase in addition the system clock speed (processor, memory, bus, and internal/external interfaces) could also increase their speeds in an extreme case to in effect allow “overclocking” of the system of the Computing Device or Companion Electronic Device in a connected mode e.g. to operate outside of its typically performance boundaries through the use of this enhanced cooling system Further changes to the performance of the system could be made depending on the system preferences such as display brightness, system element power states (e.g., audio off if no audio required), enabling/disabling ports, etc. This will allow an optimum configuration of the system based upon the application being executed on the Computing Device and or Companion Electronic Device, the available power to the system and the thermal environment of the Computing Device and or the Companion Electronic Device.

In another embodiment the computing device(s) and the Companion Electronic Device(s) can communicate to each other their respective battery and or thermal states and based upon a policy, preference or procedure can reassign the computational tasks currently being executed or scheduled to be executed to each other or to a server they may be connected to in order to reduce power consumption on either device or to reduce the thermal activity on either device or to put the activity on to a device or server which has enhanced thermal capabilities so as to more effectively deal with thermal loads in the overall system.

The upscaling/downscaling of the Computing Device or the Companion Electronic Device docked/connected system parameters could be invoked by these application-specific power availability or thermal characteristic based on one or any combination of these methods.

Additionally, Computing Device and/or Companion Electronic Device could request or require to distribute processing tasks between each other dynamically, based upon battery voltage and or thermal status for example, when the two devices come into close proximity of one another or when one's battery power is low.

In these or in other embodiments, the Computing Device and the Companion Electronic Device may additionally communicate other status information to each other in order to facilitate upscaling/downscaling or other behavior modifications, such as one device using capabilities of the other device in preference to its own. Examples of such status communications could include but are not limited to: Available general purpose processing power, availability or presence of specific processing capability (such as the presence of a graphic processing unit). available runtime or storage memory, battery capacity, peripheral availability, function availability (e.g., camera).

This invention can be implemented via specific hardware or software/firmware changes to the processors used with the computing devices and or the companion electronic devices or servers connected to them or by software on the devices by an application or at the OS kernel or firmware level or other software means or be used alone or in conjunction with the invention below to create new p states for the smart Computing Device processor when the unit is docked. It is also possible to generate multiple new p states for any processor depending on the charge levels of the batteries within the dock.

2. Solving the Issues of Higher and Lower Voltages and Powers in Multiple Devices Used in Multiple Configurations

It is critical in any mobile solution to balance performance (including speed) with the usage time between charges and to efficiently manage the thermal characteristics of the unit. This element of the invention governs the way in which the operational voltages of key components in the system are altered when the Computing Device is docked and therefore able to access an additional power source and different thermal resources. This control covers but is not limited to amending the voltage and current supply within and to the processor units and memory depending on the type of activity being performed e.g. lower voltage for playing background music, higher voltage for encoding video or playing games. It also covers the amendment of the voltage and current of processor units and memory depending on the battery charge status and also the amendment when physically connected to the Computing Device. E.g. the computing device uses a higher voltage when able to access the companion electronic device power source and able to utilize its enhanced thermal capabilities. Prior art exists for the manipulation of silicon voltage within a PC or Computing Device as a single device. The novel part of the invention is that the voltage used for a given type of content e.g. web browsing or game play will vary based on the available battery charge and can therefore be higher when the Computing Device is physically connected and able to use the thermal resources and power supply capability within the companion electronic device.

The Computing Device could have multiple or variable power supplies of different voltage, or power for example, that could be used for lower power/higher performance, etc. software and or hardware contained within the processors present with the computing device or elsewhere within the computing device and or software running on the computing device such as Firmware, RTOS, OS and or applications could enable or invoke these modes. The companion electronic device could also have multiple or variable power supplies of different voltage, or power for example, that could be used for lower power/higher performance, etc. software and or hardware contained within the processors present with the companion electronic device(s) or elsewhere within the companion electronic device(s) and or software running on the companion electronic device(s) such as Firmware, RTOS, OS and or applications could enable or invoke these modes.

This invention can be implemented via specific software on the devices at the kernel level or firmware level or be used alone or in conjunction with the invention above to create new p states for the smart Computing Device processor when the unit is docked. It is also possible to generate multiple new p states for any processor depending on the charge levels of the batteries within the dock.

The Companion Electronic Device can instruct the Computing Device to operate in particular modes and therefore to use (or not) particular Computing Device resources. Different classes of Companion Electronic Devices could instruct the Computing Device to operate in different ways. See, for example, PPC enabler architecture splits.

There may also be thermal/mechanical/electromechanical elements in the dock which are designed to work in conjunction with the Computing Device and provide additional cooling and or heat dispersion, for example to allow the Computing Device processor to operate at a higher clock rate (for example but not limited to outside of its nominal performance envelope, i.e., overclocking) without overheating than it could when not docked with such a thermal solution not present.

Alternatively or additionally, the Companion Electronic Device could invoke physical dispersion of memory usage in either the Computing Device or Companion Electronic Device. This physical dispersion of memory usage would result in heat generated by memory usage to be spread out over a larger physical area that it would be if the Computing Device or Companion Electronic Device continually accessed physically adjacent portions of memory. In addition to reducing overall heat generated, an additional benefit could lower power consumption, for example, by making the use of active cooling measures such as fans or other techniques, or passive cooling measures, less necessary. Furthermore, bill of material cost and system complexity could be reduced by the exclusion of these cooling elements. Also, the elimination of these cooling components could enable smaller, lighter, thinner and less complex devices.

Additionally, because the Companion Electronic Device contains its own processor and memory, the Computing Device will generate less heat and use less processing power than it would if it were generating the Companion Electronic Device environment as well as operating its own system. Additionally, memory, processing power, etc., that would otherwise be needed on the Computing Device to run the Companion Electronic Device environment as well as the Computing Device environment are not necessary, also enabling smaller, lighter, less complex devices.

Arm (or Other Auxiliary) Antennas

As previously mentioned, either Computing Device or Companion Electronic Device could have auxiliary antennas, or could bridge antennas, for use by the other device. In the case of a laptop-style Companion Electronic Device, for example, these antennas could be located in the display arms.

1. This can improve reception and transmission 2. A larger antenna in Companion Electronic Device can achieve same performance (or better performance) at a lower power as a smaller antenna can achieve in a Computing Device at higher power. 3. Companion Electronic Device WiFi could act as a bridge between the Computing Device and a more distant access point, improving effective throughput to the Computing Device.

Bluetooth Functionality

1. Computing Device and Companion Electronic Devices could include Bluetooth headset communication, implemented for example as a “sidebar” that docks into the device: a. The sidebar can pop out so the user can make a call 2. Bluetooth device behavior could be determined by policies, preferences or procedures. Examples include: a. The Bluetooth headset could switch on when the Computing Device rings and is answered. Bluetooth headset could be docked and switched off, then automatically switched on at an incoming call. b. Switching on at incoming call will reduce the apparent time taken to connect when the call is answered. c. Active Bluetooth headset audio could trigger a behavior of Computing Device, Companion Electronic Device or another device, for example turning off the display or music playing while in call.

Wi-Fi On/Off

Computing Device and/or Companion Electronic Devices could include WiFi or other wireless communication capability. The devices could allow for WiFi functionality to be managed in common.

WiFi provides an alternative to the Computing Devices cellular connection. It provides many advantages to both the user and operator in reducing cost. The disadvantage of WiFi is that it requires a relatively high current and therefore has a significant negative impact on battery life. This invention maximizes the use of and users control of WiFi as a lower cost connection whilst protecting the overall battery life.

Could implement policies to turn on or off WiFi based on Computing Device/Companion Electronic Device configurations, and location or other methods. For example, a feature could enables the Computing Device to switch off the WiFi in the Computing Device. This and other WiFi functionality could be controlled through preferences, policies and procedures. Examples include:

-   -   User can turn WiFi on and off with a physical switch in the dock         or a software switch based on connection to the dock     -   The WiFi status, i.e. on or off, will be visible to the user at         all times through use of either an LED on the dock or message or         icon on the screen of the dock and/or Computing Device.     -   User can set WiFi to be the preferred connection if available     -   When the Computing Device is roaming or in a specific location         (detected by the cellular network or cell ID on which it is         camped) the Computing Device can select WiFi as its preferred         connection automatically and turn on the WiFi radio. This will         significantly reduce data roaming costs when a WiFi connection         is available. When it sees its home network code again it will         turn off the WiFi radio if the user has set the default state to         be WiFi off to conserve battery performance.     -   When it is physically docked and able to access greater battery         power the Computing Device can enable WiFi automatically or         based on instruction from Companion Electronic Device. The         Companion Electronic Device can send differentiated instructions         based on information provided by the computing device and or         Companion Electronic Device.     -   When it detects that external power is connected the Computing         Device can switch on WiFi automatically or be instructed to by         the Companion Electronic Device to do so.     -   When the battery levels fall below a preset level in the         Computing Device and/or dock WiFi can be switched off by the         software in the Computing Device or the Companion Electronic         Device unit to reduce current drain.     -   An application could include an enable/disable WiFi” function         that will allow the Computing Device to turn on or off the WiFi         radio based on the nature of the operation being performed. E.g.         when the web browser is launched it will turn on the WiFi radio         but when the page is closed the Wifi hardware and software will         be shut off to conserve power. This function could also be made         available to third party application developers via an API.     -   WiFi on/off based on location as derived from cell ID, GPS, or         other, etc.

Signal-Less Display

Future embodiments of the phone powered computing concept may have a wireless display to allow the display to fully rotate, be separate or to be removed from the Computing Device, e.g.,

-   -   Tablet style device with optional full hard key keyboard and         mouse     -   Wireless optional module, also referred to as PhoneWrap, that         may contain additional batteries, enhanced antenna, other         electronics.

Multi-Modal Opportunities

Different types of Computing Devices and Companion Electronic Devices have their own characteristics, such as different screen sizes, input methods, etc. The multi-modal PPC solution allows both Computing Devices & Companion Electronic Devices to work with essentially infinite different Companion devices, and in many different ways.

Some examples of the multi-modal nature the PPC concept include:

1. The device can be all in one, or different modules can be applied for different personalities. 1.1. “Device” could be Computing Device or Companion Electronic Device or other devices. 1.2. “Module” could be a software module or a hardware module, or a combination thereof including but not limited to as referred to in other embodiments in this document. 1.3. “Personalities” could be combination user environment elements, form factor, user interface look or feel, user interface type, power profiles, processing profiles, data access profiles, user configuration profiles (different display, audio, I/O) etc. 2. Modal use cases may include, for example: 2.1. Companion Electronic Device alone—In the “Smart Computing Device/Smart Companion Electronic Device” embodiment, Companion Electronic Device could operate on its own without connecting the Computing Device since it has its own OS, processor, memory, etc. The Companion Electronic Device could also run its own apps 2.2. Computing Device as a master 2.3. Companion Electronic Device as a master 2.4. Computing Device with multiple Companion Electronic Devices 2.5. Computing Device as modem for Companion Electronic Device. For example, Companion Electronic Device providing additional wired or wireless connectivity for Computing Device Computing Device used independently while connected wired or wirelessly to the Companion Electronic Device, e.g., answer a call with Computing Device Computing Device as input device peripheral for the Companion Electronic Device, e.g., transport controls for video, game controller, mouse, etc., or vice versa, for example, as a “phone mouse”: 2.5.1. The Computing Device can become a mouse (e.g., using the camera in the Computing Device to detect movement in 2D or using sensors to detect movement in 3D) and could have: 2.5.1.1. An accelerometer 2.5.1.2. An optical sensor 2.5.2. The mouse can allow rotational push/pull/zoom/reduce/pinch etc 2.5.3. The Computing Device can be used to “throw” or “flick” pictures or files to the Companion Electronic Device or other devices/units 2.5.3.1. Using sensors 2.5.3.2. Using touchscreen 2.6. The Computing Device can be used in place of a stylus for a touch based Companion Electronic Device display, e.g., by “writing” in the air using sensors to detect movement 2.7. Computing Device could be a remote pointing device 2.8. The Companion Electronic Device can be used as the Companion Electronic Device for multiple Computing Devices 2.9. Sharing/synchronization of data between Computing Device and Companion Electronic Device 2.10. Copying of Computing Device memory to Companion Electronic Device for use independently of Computing Device 2.11. Copying/sharing/using of Computing Device memory for use while Computing Device is connected 2.12. Copying back to the Computing Device and/or the companion electronic device sync 2.13. Security provision, e.g., persistence of data on Companion Electronic Device only while connected to Companion Electronic Device for public kiosk scenarios; private device with permanent persistence; or access to certain classes of data (based on profile settings in either Computing Device and Companion Electronic Device) could be stored on the Companion; data permanently stored on the Companion Electronic Device could be secured and tied to a particular device 2.13.1. SQL or other method could be used to manage file systems 2.13.2. SyncML or other method could be used to sync data between devices 2.13.3. Backup of Computing Device data on Companion Electronic Device to local or peripheral memory 2.14. Gaming mode—Computing Device and Companion Electronic Device could work together in a gaming mode to enable gaming on a larger display. Variations could include 2.14.1. Wired or wireless video/display transmission from Computing Device to Companion Electronic Device to vice versa 2.14.2. The use of wired or wireless gaming controller peripherals as input devices to the Companion Electronic Device or Computing Device operating as a gaming controller for Companion Electronic Device or vice versa 2.14.3. Multiple Computing Devices or Companion Electronic Devices connected for multi-player gaming 2.15. TV mode (10 foot mode)—User environment adapted for a typical living room/television set-up where the display screen and input controls are relatively distant from the user and where there may be multiple users/viewers. This mode is contrasted with, for example, a desktop computing-style mode where the display screen and input controls are relatively close to the user and the user is more likely to be alone. Key adaptations include ensuring that the graphical user interface is legible and comfortable to use at the relatively far distance and that input controls are within reach of the user. Example adaptations may include: 2.15.1. Larger text in the GUI 2.15.2. Re-layout of the GUI, especially simplification 2.15.3. Replacement with alternatives of input methods that require close proximity, such as touchscreen, with those that do not, such as cursor or pointer control 2.15.4. Wireless or otherwise more convenient input controls such as keyboards, trackpads and remote controls

Furthermore, TV mode may optimize the experience of typical living room use cases, such as streaming media consumption, by for example, prioritizing those tasks above other system tasks which may be less important for the usage environment, such as realtime incoming email handing.

Also, notification or other behaviors may be adapted to the usage environment. For example, text message or email previews may be displayed on the screen automatically in a handheld or desktop usage environment, where the user can reasonably expect privacy. In TV mode, however, it is more likely that the user may not have privacy and may, therefore, wish that message preview not be displayed. In this example, TV mode could include discrete notification of incoming messages without displaying previews or correspondent details.

2.16. Video conference mode—For example, Computing Device could be held by the user in order to use its microphone instead of relying on a remote mic or mic array on Companion Electronic Device

-   -   See more about video conference mode in the next section,         Multi-use display and camera.         2.17. The Computing Device can be a projector         3. In the “Smart Computing Device/Smart Companion Electronic         Device” embodiment, Computing Device doesn't need to know         Companion Electronic Device's characteristics         3.1. Required software on the Computing Device could be         application level rather than below application-level changes,         making it more likely that Companion Electronic Devices could be         used generically with “any” Computing Device         4. Modes for multiple users—Useful for families and small         businesses and schools         4.1. For small businesses and schools only a few Companion         Electronic Devices will be needed, so employees and students         just plug in at work/school, and take home their work to plug in         at their Companion Electronic Device home device.         4.2. State persistence         4.2.1. The Computing Device or Companion Electronic Device could         include permission profiles, for example, to block Facebook at         work, or parental controls, access through corporate firewall at         work         5. Could be ruggedized device adapted to its environment         5.1. Computing Device could dock into ruggedized Companion         Electronic Device dock, for example with a resistive keypad that         can be used with gloves, such that an unruggedized Computing         Device is transformed into a ruggedized Companion Electronic         Device The Companion Electronic Device could also expand         capabilities of Computing Device as a work tool, for example.

6. Multi-docking

6.1. The Computing Device can be docked into (wired or wirelessly connected with) multiple Companion Electronic Devices including: 6.1.1. A display

6.1.2. TV

6.1.3. Large home/office display

6.1.4. Keyboard

6.1.5. Wireless charging pad 6.1.6. Induction charging pad 6.1.7. Any other type of device as mentioned throughout this document or other types of devices

Multi-Modular Concept

A user may be looking for the low cost, optimal performance and portable solution for a given usage case. The nature of the solution will vary between users and even for the same user in different scenarios. This variety means that a modular based approach may provide the greatest utility.

For example, a tablet style device.

In a low cost embodiment the Computing Device will physically dock with the display utilizing all the key components of the Computing Device (accelerometer, compass etc.). This would be an example of an “all in one solution”. However the user may wish to keep the Computing Device easily accessible to be able to receive calls whilst using the tablet and choose to connect to the display with a wireless connection. The user will then slide a wireless module into the tablet in place of the Computing Device, enabling wireless connectivity to the Computing Device.

The wireless (or other) capability of the Computing Device may not be sufficient to provide the performance that the user requires in which case an accessory, referred to as PhoneWrap is connected to the Computing Device to improve amongst other things its battery and antenna performance and additional wireless radios if required.

Alternatively, Computing Devices may connect directly without the need for a phone wrap device to a Companion Electronic Device, if it has sufficient capability to do so.

Finally, the user may wish to connect additional speakers, keyboards or other peripherals to the Computing Device or Companion Electronic Device. The elements when used together form a multi modular concept.

-   See also possible form factor & use scenario figures.

Computing Device could also be used in a laptop like configuration, either docked or wirelessly connected. If Computing Device is not sufficiently capable, the same PhoneWrap could be used with a laptop like solution already described hence the modules can be reused in multiple embodiments.

A further embodiment could be to connect Computing Device to a television or monitor, possibly with an keyboard, trackball or mouse.

Additional configurations of the multi-modular concept include:

1. The user can choose different parts for different uses/preferences (e.g. gaming, office, small business, family). It will be possible to incorporate an Atom processor (or similar, such as an ARM- or MIPs based or other processor) into the Computing Device or Companion Electronic Device, and/or add Windows or other operating systems to a Computing Device or Companion Electronic Device. 2. There could also be 2 or more cores in the Computing Device or Companion Electronic Device, which can be plug-ins. 2.1. Further processing improvements could be provided for Computing Device by Companion Electronic Device or vice versa, for example to render complicated graphics on Companion Electronic Device that are sent back to Computing Device, this could be useful to reduce the thermal load on the computing device 2.2. Companion Electronic Device could instruct Computing Device to dedicate cores in certain use modes, such as gaming. 2.3. Multi OS and multiple core architectures could be managed by a number of different methods, for example using a hypervisor or other form of software or hardware virtualization.

-   -   Multiple embodiments of these options are shown in the HIV/OS         and SW system diagram, FIGS. 17-25.         3. The Computing Device could take on a context-dependent role         that could take advantage of the combined capabilities of         Computing Device and Companion Electronic Device. For example,         Computing Device could be an advertising or information module,         so that the Computing Device shows ads or products (or different         personalities) (or links) when a movie or show is playing.         3.1. Enables functionality based on context. For example,         because more activities take place through Computing         Device/Companion Electronic Device, more is known about the         user's preference and activities, becoming more valuable to         advertisers, for example. Computing Device or Companion         Electronic Device could use information provided the other or         the combination of the two.         3.2. Other examples of functionality based on context include:         Recommendations for goods, services or activities, based on         present or past behaviour or context. For example:         3.2.1. Browsing or media consumption information from Computing         Device could be used for EPG viewing recommendation on a         television Companion Electronic Device.         3.2.2. Information regarding activity (shopping, content         viewing, etc.) on a Companion Electronic Device could be stored         on a Computing Device and later combined with location         information, for example to:         3.2.2.1. Provide nearby shopping or dining recommendations         3.2.2.2. Offer deals at nearby bricks and mortar outlets for         good browsed online.         3.3. Content augmentation, for example, additional information         about a program that you are watching.         4. Other products can be plugged into the device(s), including         but not limited to:

4.1. Plug-in Femtocell Board 4.2. Plug-in Picocell Board

4.3. Plug-in Wi-Fi unit 4.4. Plug-in TV tuner 4.5. Plug-in large scale projector 4.6. Plug-in wireless receiver 4.7. Plug-in iPod/music player dock 4.8. Other peripherals as described throughout the document.

In whole or in part, these additional products, may form part of the PPC system and can be used to implement some of all of the embodiments incorporated in this document.

Multi-Use Display, Camera & Sensing

The displays, cameras, and sensing capabilities of Computing Device and Companion Electronic Device could be used in multiple ways, including:

1. Presentation mode 1.1. Where the display can be turned around so others can see the display. See, for example, FIG. 33. 1.2. The Computing Device can be used by the presenter as the key device (allowing for example, notes and prompts to be seen by the presenter but not the audience). 1.3. The Computing Device and Companion Electronic Device can run in parallel for a presentation, so the viewer(s) looks at the slideshow/presentation on the Companion Electronic Device display, but also looks at the presenter on the Computing Device display. The presenter talks to and controls the presentation and can point to the device as it knows where it is. The Companion Electronic Device may also display holographic images of the presenter. 1.3.1. The holographic image projection could, for example, allow the presenter to be “present” at the point the where the presentation is being viewed while in reality being physically located somewhere else. 1.3.2. The Computing Device could be used as a controller for the presentation. (See “phone mouse” discussions.) 1.4. Multi-use display modes for the “Smart Computing Device/Smart Companion Electronic Device” embodiment may take advantage of fundamental capabilities of the concept, e.g., 1.4.1. Computing Device and Companion Electronic Device could swap roles. 1.4.2. When docked or on instruction from Companion Electronic Device, the Computing Device could adapt its behaviour, for by simultaneously generating both the UI elements required of it by Companion Electronic Device along with a local UI on the Computing Device display. This local UI may or may not be related to the Companion Electronic Device's user environment or an application running on the Companion Electronic Device. 1.4.3. Additionally, Companion Electronic Device could send data and/or UI elements to Computing Device for display on the Computing Device screen, for processing, or for storage/sync, concurrently or not currently to activity of the Companion Electronic Device. 2. Modal dual screen use cases, e.g., 2.1. Windows or notifications “pop up” on Computing Device display instead of Companion Electronic Device display, e.g., for privacy or convenience 2.1.1. This behavior could be based on policy or user preference or a user action to transfer the window from one display to the other. 2.2. In video conference mode, a first image displays on Computing Device while a caller's image is displayed on Companion Electronic Device, or could display more callers in a conference on Companion Electronic Device than would fit on a Computing Device screen. 2.3. Location/position information of the two devices relative to one another could be tracked to determine changes in their relative position or location. Location, position and movement information could be from any single or plurality of methods, e.g., GPS, cell-ID, signal strength, accelerometers, altimeters, e-compasses, cameras, microphones/speakers (e.g., for ultrasonic) or other sensors or systems. Use case examples include: 2.3.1. Using one device as a multi-axis controller for the GUI or other UI of the other device. 2.4. Supporting proximity processing/display use case covered elsewhere in the document, such as: 2.4.1. Distributing processing tasks between Computing Device and Companion Electronic Device 2.4.2. Display UI elements or information on one display or the other. 2.5. Supporting security policies, for example “unlocking” capability or data on one device based upon a security key, preference, policy or procedure when the other device comes within a given distance of the other 2.5.1. Security challenge and or access control could appear either on Computing Device or Companion Electronic Device based on policy 2.6. Positioning could use the two cameras to detect deltas in images between the two devices. 2.7. Use position or orientation of one device to control the relative position or orientation of information available to or displayed on the other 2.7.1. For example, 3D TV requires the user's eyes to be horizontally aligned with the TV. You can't, for example, lie on your side to watch 3D TV. One device could be on your person—for example, Computing Device as glasses or a phone in your pocket. When the orientation of that device moves out of horizontal relative to the TV or other display, the first device could relay its orientation to the second device. The second device could adapt its orientation to match that of the viewer. This could be accomplished by physically moving the display, for example with a motor, or by adapting the orientation in software. 3. The system could decide, based on policies or user settings, to display information on the Computing Device screen or Companion Electronic Device screen, or transfer from one to the other based on modal scenarios, e.g., walking in and out or close proximity of Companion Electronic Device while holding Computing Device 4. Augmented reality mode—A “reality”, e.g., a video image, captured on Computing Device could be displayed and augmented with information or interactivity on Companion Electronic Device, or by a server connected to either the computing device or the companion electronic device with the augmentation being either done or displayed on the Computing Device or Companion Electronic Device. 5. Gaming mode 5.1. An accelerometer is incorporated in the display of Computing Device and/or Companion Electronic Device allowing it to be used as a gaming device, navigation or pointing device 6. Scanner/Camera—The display can be rotated so the camera can be used as a scanner. Camera use cases include: 6.1. Biometric security, e.g., facial recognition, or fingerprint, iris recognition 6.1.1. This could be used in combination with proximity detection of the computing device and or the companion electronic devices 6.1.2. This could also be used in conjunction with another key or token in the computing device and or the companion electronic device. 6.2. Augmented reality use cases 6.3. Barcode scanning

6.4. Magnification

6.5. Use one device's camera to act as a light sensor, for example to provide information to automatically adjust the other device's display brightness 6.6. As a mouse to sense movement or “clicks” by moving the finger or covering the lens, this information to be used by the computing device and or the companion electronic device or both or by a server they may be connected to 6.7. As stated elsewhere, the two or more cameras could be used for video conferencing use cases 6.8. The two devices' cameras could be used in conjunction with one another to capture 3D video. 6.9. One device's LED “flash” could be used by and or controlled by the other or in conjunction with the other devices camera, for example, providing supplementary light 6.10. Use one device's camera as a scanner (fixed or handheld) for the other device. 6.11. The camera on the computing device or on the companion electronic device can be used in a video conference mode—in this mode a high resolution fixed focus camera or other camera present on the devices might have alternate parameters or it might have its image post processed to compensate the requirements of video conference mode operation such as having the subjects at a further distance from the camera or adopting a wide angle view. 6.12. The cameras on either the computing device and or the companion electronic devices can be used to adjusts factors such s the display brightness and contrast dependent on the ambient lighting conditions as detected by cameras on either the computing device and or the companion electronic device the device can adjust its own display and the other devices displays. In another embodiment of this invention the cameras and applications running on either the computing device or the companion electronic device can work together or combination based upon the type of applications being run and or displayed on either the computing device or the companion electronic device to adjust the display or other characteristics of the computing device and or the electronic computing device.

Environment Switching & Management

This allows the user to switch environments from one device to another; the computing device and or the companion electronic device allow and enables the storing of the device state or device status of themselves respectively and or each other.

Device Status may refer to, for example current hardware or software settings or requirements of any of the devices in the system, which may be related to the usage environment of any of the devices, including for example, the Computing Device, the Companion Electronic Device or another device such as a server.

Device State may refer to, for example, the past, current or scheduled/planned activities running on the device, such as the fact that the web browser is open and the page which is being viewed or the recently viewed page history. This may be the device state of any of the devices in the system, including for example, the Computing Device, the Companion Electronic Device or another device such as a server.

1. RTOS

1.1. Peripherals, configurations, preferences, etc. in or connected to one device, e.g., a printer, WAN connection preference, could appear as if they are in or connected to the other device. This can work in both directions.

2. OS

2.1. OS, elements or updates could be loaded from one device to the other 2.2. OS execution could be distributed between the two devices 2.3. Preferences and settings, including registry settings and user preferences 2.4. Extend the capacity, capability and features of the OS in one device with others that are available in the other device (s) 3. Applications—As mentioned elsewhere applications could: 3.1. Switch execution between the computing device and or the companion electronic device, running one device's application on the other, or on a server. 3.2. Application status or data is acquired from the computing device and or the companion electronic device and or a server to be used with a running application on the computing device and or the companion electronic device and or a server 3.3. Application capability can be extended to take advantage of additional resources. See, for example, Android Fragments discussion, and examples of one device using the resources of the other or on server 3.4. Applications could also limit capability, e.g., if a required hardware component is not present in the computing device and or the companion electronic device. For example, a music player that enables track switching based on a shake of the device as detected by sensor could remove this capability when being display on a computing device and or the companion electronic device that lacks that hardware capability. 3.4.1. Applications could also provide for an alternative way of accessing functionality if the usual way is not present in the second device. In the above example music track switching could instead be enabled through, for example, a hardware key present on the second device. 3.5. Data & files 3.5.1. See also discussions of data access, transfer, security and sync elsewhere in this document. 3.5.2. Data & files from the computing device and or the companion electronic device and or a server could be made available to the other the computing device and or the companion electronic device and or a server unhindered, limited or fully open through preferences, procedures or policies.

3.6. GUI

3.6.1. See also elsewhere in the document for options regarding GUI creation and management between Companion Electronic Device and Computing Device. 3.6.2. Sharing, switching or modification could be in whole or in part (or not at all) though preferences, procedures or polices. 3.7. Physical elements, e.g., input/output controls or components 3.8. Display preference, e.g., which elements to show on which device's display 3.9. Settings & preferences 3.9.1. Setting and preference information of Computing Device(s) or Companion Electronic Device(s) could be made available to the other of Computing Device(s) or Companion Electronic Device(s), either partially or fully, modified or unmodified based on preferences, policies and procedures. 3.9.2. The computing device(s) and or the companion electronic device(s) may also have alternative configurations, settings, or preferences that come into play when the devices are connected, enabling an enhanced configuration that is not available or relevant to either device independently. 3.9.3. Settings and preferences may also control the behavior of either the computing device(s) and or the companion electronic device(s) and or server(s) connected to either of them. 3.9.3.1. For example, Computing Device(s) or another device might prompt settings changes on Companion Electronic Device(s) to adapt the GUI display to the user's particular want or need, for example, to increase font size if the user has impaired eyesight or to increase loudness if the user is hard of hearing. 3.9.3.2. Another example of this concept would be to apply cosmetic UI settings such as colour, wallpaper, etc., on the computing device(s) and or the companion electronic device(s) based on settings from the other. 3.9.4. Switching could be initiated by user action or by policy settings or both 3.9.5. Peripherals, configurations, system or user preferences, etc. in or connected to the computing device(s) and or the companion electronic device(s) and or a serve(s)r, e.g., a printer, WAN connection, preference, could appear (modified or unmodified) as if they are in or connected to one or more of the other devices. This can work in both directions. 3.9.6. Companion Electronic Device(s) environment could be switched on (enabled) or skinned to match the look and feel of the Computing Device(s). For example, if the Computing Device is an iPhone, the Companion Electronic Device environment, including locally generated elements, could adapt itself to mimic the look and feel of related operating systems/UIs. By the same principle, Companion Electronic Device could adopt a Windows, Android, Chrome or other looks and feel based on the type of connected device.

-   See also earlier state retention, persistence, etc., discussions.     4. Companion Electronic Device user experience could be transferred     back on to Computing Device(s)     5. Data and state information could be retained in both directions:

5.1. From Computing Device(s) to Companion Electronic Device(s)

5.2. From Companion Electronic Device to Computing Device, e.g., walk away using Computing Device with the email that you were writing on Companion Electronic Device

Independent Display Management

This allows independent management of displays in the Computing Device or Companion Electronic Device or other devices/units, such as peripherals devices or a server(s)

In this embodiment of the invention the independent management of the displays provides for one or more of the following, which could be initiated by Computing Device, Companion Electronic Device or another device, such as server, according to proximity, preference, policy, procedure an event or a user action:

-   -   One display to be turned off while the other is (or, others are)         on. The different displays to be different resolutions     -   The different displays to be different sizes     -   The different displays to use different display parameters such         as contrast, brightness, color saturation, etc. levels triggered         for example, by a software program receiving data by sensors,         cameras, policies procedures, content type, application type,         algorithms, user settings, etc.     -   The different displays to show different views, information or         content from the same application     -   Controls for a video player on the Computing Device and the         video itself on the Companion Electronic Device screen     -   Magnification of content on one screen of the other     -   Two different views of a game, for example from each player's         perspective     -   An EPG on one device, possibly with program preview, while         watching content on the other.     -   The different displays to show views, information or content         from different applications at the same time. E.g., the         Computing Device to show an SMS message that has just been         received and the Companion Electronic Device screen to show a         video. For example:     -   Answering a call on the Computing Device while browsing or         watching a video on the Companion Electronic Device display     -   Controlling music playback from the Computing Device while         browsing on the Companion Electronic Device     -   The different displays can be used together, for example to         physically extend a single view across multiple displays     -   One display could be used to show subtitles in a selected         language for video content being watched on the second display.         This use case could also work in public settings such as a         cinema where the cinema media system, the associated audio         system, etc., acted as a Companion Electronic Device. A         variation of this idea could also or instead transmit an         alternative audio track, for example in a different language,         for listening through a Computing Device, for example with         headsets in a public cinema.

This independent control is achieved by software on the Computing Device and/or Companion Electronic Device, for example alterations to the driver, library or kernel layers of the Computing Device and possibly the provision of one or more API's for Application Developers to access the operational modes above. Computing Device and/or Companion Electronic Device can also manage/change/generate display attributes and characteristics dependent on activity, conditions or characteristics of the other device.

Multi-Token Interaction

The device can interact with other types of token, including by way of example only:

-   -   Bracelet     -   Ring     -   Pen     -   Magnetic/smart card     -   ID badge     -   Any Wirelessly enabled device including Computing Device or         Companion Electronic Device themselves

An embodiment of multitoken interaction could be through incorporation of NFC capability into Computing Device or Companion Electronic Device. Information exchanged could include profile, security or access rights and could be used to enable or disable specific functionality on the Computing Device or Companion Electronic Device. Examples include:

-   -   Payment     -   Internet content access restriction     -   Font size and other UI elements, e.g., for the visually impaired     -   Audio or subtitle settings, for example for the hearing impaired         or for use in an alternative language.

Another embodiment is that the above and other examples could be enabled by the Computing Device and Companion Electronic Devices themselves corning in close proximity of each other.

Hot-Swappable Cells

2 or more batteries on the front, back or sides with hot-swappable cells.

In many but not all embodiments, it is intended that the Computing Device or Companion Electronic Device be a mobile solution and hence will require their own batteries as well as the ability to connect to an external power source. These batteries can also charge or be charged by the other device's batteries, including but not limited to Computing Device or Companion Electronic Device. As there may be several separate batteries or battery cells these will also be able to be “hot swapped” meaning that a one or more batteries can be removed without losing power to the Companion Electronic Device or Computing Device even if no external power source is available. The battery can then be replaced with a different charged battery. Individual batteries that have been replaced can then be charged by use of a separate charging station or by reinserting them in the dock and connecting the dock to an external power source or by the other batteries.

This embodiment is considered unique because phones and PC's today do not contain “hot swappable” batteries and lose power if the battery is removed without an external power source connected.

Automatic Back Up

Back up could take place immediately when you plug in the phone and or other Computing Device/Companion Electronic Device type. Alternatively, this could take place with other alternative connection methods, including wireless.

As the Computing Device becomes a replacement for your PC it is essential that a range of backup options are available within the PPC concept. Here the term “plug” can be defined as a physical or wireless connection. Existing solutions do not rely on the docked status of the Computing Device or Companion Electronic Device to trigger the back-up process.

The options include:

-   -   Limited content (the user specifies the content types to be         backed up in the PPC settings applications) back up to:     -   Memory within the Computing Device/Companion Electronic Device     -   External memory via USB or other connection to the Computing         Device/Companion Electronic Device     -   Back up to a server over a private home or office network—in         this option WiFi could be enabled automatically to reduce data         costs and off load data from the Operators network. If the user         has turned WiFi off in their Computing Device it will then turn         off automatically once the back-up is complete.     -   To cloud based storage via WiFi or cellular connection.     -   Full content back up     -   Memory within the Computing Device/Companion Electronic Device.     -   External memory via USB or other connection to the Computing         Device/Companion Electronic Device     -   Back up to a server over a private home or office network—in         this option WiFi will be enabled automatically to reduce data         costs and off load data from the Operators network. If the user         has turned WiFi off in their Computing Device it will then turn         off automatically once the back-up is complete.     -   To cloud based storage via WiFi or cellular connection.     -   This back up is a background function that could run with a         defined task priority within the operation.     -   There could be a visual indication to the user that the back-up         is taking place such that the user will not disconnect the         Computing Device from the Computing Device/Companion Electronic         Device (physically or wirelessly) without understanding that the         back-up is not yet complete.

The back-up process could be initiated as soon as the presence of the Computing Device/Companion Electronic Device is detected by the Computing Device or vice versa. The user will select the destination and content types for the back-up storage in the settings part of the software that runs on the Computing Device or Companion Electronic Device.

When data is backed up to a source that may be deemed by the user as “less secure” e.g. a memory card it will be possible to encrypt all or some of the data or add a security code to access it. This security code could be as simple as data from the users SIM card or a 4 digit user code. Some organisations are likely to want a far more secure access in which case an application on the Computing Device will encrypt all data prior to storing it with a key based algorithm that will also be required to read or restore the data stored.

Back-up could also extend to back-up of the memory of other connected or integrated devices, for example the content of a SIM card or the content of a connected USB flash drive or memory card.

An alternative or additional embodiment of the automatic backup capability would be for the system to automatically back up Computing Device to Companion Electronic Device or vice versa when wireless signal strength began to degrade. Signal strength degradation (as measured by RF power, quality of service, bit error rate or other metric) could indicate that the user was taking one device out of range of the other. The backup could instead be automatically prompted, giving the user the opportunity to agree to backup and to remain within the coverage area until the backup is complete.

In the case of a non-wireless connection, the system could prompt for back-up before the device is physically disconnected. If no removal prompt is required before disconnection, the system could prompt the user to reconnect the device for back-up/sync following a disconnection if back-up/sync were not complete.

Similarly, automatic or automatically prompted backup could also be triggered by other cases such as:

-   -   Low battery on Computing Device or Companion Electronic Device     -   Switch off of either device (back up before completing switch         off)     -   Application closure or application sent to background     -   Reaching a given threshold of amount of data added or changed     -   A set amount of time between back-ups having passed

Automatic backup behaviour could be determined by preferences, policies or procedures. This could include monitoring the amount of data changed or added and triggering backup either with any change or with change of a set amount or percentage.

This embodiment could be especially useful, for example, in a public Companion Electronic Device “kiosk” scenario to ensure that all changes or additions were backed-up and synchronized to Computing Device before the user left the public kiosk.

In another embodiment, as mentioned elsewhere in the document, automatic back-up could take the form of periodic or continuous data and or software (including but not limited to OS, apps, etc.) synchronization between, for example, a mobile Computing Device and a home, office, network or cloud (e.g. a server) based Companion Electronic Device (or vice versa), in order to ensure data consistency between or among the devices. This back-up could be triggered and managed as with any of the above methods, or with other methods.

In the case that the devices are not in proximity with one another but each has a connection to the internet (or to another public or private network), the devices could be periodically or continuously backed up and/or synchronized via that network connection based on preferences, policies or procedures and/or some or all of the above methods.

Bumped Up Camera

-   See also multi-use display, camera and sensor section and     Independent Display Management section. -   See also Computing Device/Companion Electronic Device peripheral     device management and sharing throughout the document.     1. “Bumped up” refers to higher capability, performance, etc., that     is modal     2. Computing Device and Companion Electronic Devices could each have     any number of their own cameras which could be used independently or     in conjunction with one another to perform various functions which     could include but are not limited to any of the following use cases.     These use cases are enabled by the novel combination of cameras from     two or several different devices in the PPC system, which could be     managed in whole or in part by software residing on Computing     Device, Companion Electronic Device, both, or another device.     2.1. Taking photos, including 3D or panoramic, taking advantage of     the combination of Computing Device and Companion Electronic Device     or Cn cameras     2.2. Capturing videos, including 3D, taking advantage of the     combination of Computing Device and Companion Electronic Device, or     Cn cameras     2.3. Video calling or conference calling     2.3.1. This could include taking advantage of multiple Computing     Device and Companion Electronic Device or Cn cameras to each capture     a different caller or callers' image which could then be combined or     aggregated in software. For example, two users on one side of the     call could be captured respectively by the Computing Device and     Companion Electronic Device cameras while sitting in different parts     of the room or in different rooms. The separate callers' images     could then be combined in software into one calling view that is     sent to the user on the other side of the call. The link between the     devices and by extension their cameras could be a direct link or     could be through an intermediate device such as a server.     2.3.2. In another embodiment, a user could, for example, use one     camera to send an image of something else, for example a salesperson     to show to a prospective purchaser, a product alongside an image of     themselves as captured by a second camera.     2.3.3. In another embodiment, multiple cameras could be used to     capture a 3D image stream from transmission to the other caller.     2.4. Webcamming—Video calling and video conferencing examples could     also apply to webcamming.     2.5. Authentication or other security features as mentioned     elsewhere in this document     2.6. In games, for example to track device or user movement or to     provide a background image or game field for the gameplay     2.7. Motion detection, such as for security     2.8. Other multi-camera use cases such as a “mirror” to see behind     you by, for example, aiming the Computing Device camera at your back     while looking at the image for that camera in front of you on     Companion Electronic Device.

Security Features

The PPC concept enables and could be supported a number of security features, including:

1. Remote kill—to enable remote killing of one or both or all devices 1.1. Remote kill could include deleting data on the remote device, disabling communication, rendering the remote device completely unusable, or any combination of these or other actions. 1.2. Remote kill could be manual or automatic, and it could be triggered by any number of preferences, policies and procedures. 1.3. Remote kill could be combined with the automatic back-up feature to back-up content on the remote device to another device or server prior to deleting the data on the remote device with remote kill. 1.4. Remote kill could benefit from the previously mentioned preference back up as well as app, sw, OS and data backup/synchronization, for example retaining the state of a lost or stolen remote device. This state could then be applied to a new replacement device. 1.5. Remote kill could include “killing” of any connected or integrated devices, for example USB flash drives or memory cards. 1.6. Further, remote kill could us the retained internet connection of the local device, for example Companion Electronic Device, to kill any services associated with that device. For example, this could include automatic notification to add the device's IMEI and/or IMSI (or equivalents) to a lost/stolen service blacklist. 2. Synchronisation—Computing Device can synch with Companion Electronic Device or vice-versa and/or with other devices and/or with the cloud. It can be all devices or just some.

-   -   See also earlier discussions of synchronization.         3. Authentication—See earlier description under camera and         multitoken. Other examples include:         3.1. Separate passwords for Computing Device and Companion         Electronic Device that combine to form an authentication key         through a software method to allow permissions specific to that         combination of Computing Device and Companion Electronic Device.         Companion Electronic Device could have a common password to be         used with many different Computing Devices or independent         passwords.         3.2. In an embodiment a teacher could have a Companion         Electronic Device password that, together with her Computing         Device password, would enable administrator access while pupil's         Computing Device passwords with the same or different Companion         Electronic Device passwords would only allow restricted access.         3.3. In another embodiment, a service technician's Computing         Device and Companion Electronic Device password combination         could enable a service mode at a public kiosk Companion         Electronic Device.         3.4. Voice print authentication in isolation or combined with         any other authentication method could be enabled with a         Computing Device, for example, for access to a Companion         Electronic Device that does not have its own microphone.

Wireless Video/Display and Data Transmission

Wireless connections between Computing Device and Companion Electronic Device (and also other devices) could offer many practical and convenience benefits compared to wired connections. For example, a Computing Device could be left in a briefcase and or a pocket while accessed through a Companion Electronic Device. Or a tablet-style/notebook style/display Companion Electronic Device could be made especially thin and light without the need to physically dock a Computing Device into it.

However, wireless video/display transmission, especially, presents challenges. The connection between the devices must be robust, of sufficient bandwidth or if bandwidth is limited use techniques such as real time compression to reduce the signal's bandwidth requirements the use of compression can cause problems in situations where low latency is required such as gaming and or GUI interactions such as pinching or zooming on a Companion Electronic Device display, In many embodiments of Companion Electronic Device's video/display transmission, audio and use input/output events will be done concurrently also be sent in the same and/or opposite direction, and may require the adoption of a schema. This schema could use standardised protocols such as H.264 and MP3 for video and audio encoding and standardised USB protocols for data transmission and the passing of control signals between the Computing Device and the Companion Electronic Devices. Furthermore, other video or data streams, such as a live camera video stream, may also need to be sent concurrently. Such systems could also use non standardised or proprietary protocols to function

In a wireless embodiment, wireless video transmission with low latency could be achieved using:

1. IEEE 802.11n or similar point-to-point connection between Computing Device and Companion Electronic Device. 2. A transmitter/receiver combination/system that has the required bandwidth and power to transmit and receive video/audio and data between the devices, this system may or may not use encoding techniques to allow for multipath and or other radio effects which could cause the received signal to be corrupted. 3. A progressive transfer mechanism that encodes and transfers a frame in portions, e.g., 1/10 horizontal slices, rather than frame-by-frame. 4. Dynamic reduction in Frame rate and in resolution dependent on the usage scenario with an application such as Gaming for example in certain game play modes or within a game mode display resolution and or frame rate may be reduced and or increased thus altering the bandwidth and hence compression requirements and consequently reducing latency of the system, as with less Information to compress the compression process can be executed faster. 5. The system could down scale video on the transmission side for example from Computing Device to Companion Electronic Device with downscaling happening on the Computing Device and then upscaling on the Companion Electronic Device after the video has been received (post processing) to restore the quality of the original source video—this downscaling/upscaling could be done through simple techniques such as reducing the scan rate of the video signal (or a data representation thereof) it could also be done by line skipping e.g. transmitting only the odd or even lines in a frame. 6. The techniques described in 5 could be augmented by adding information regarding the frame such as the number of lines of the original source e.g., it was 1080 P or colour/contrast information this could be transmitted along with the video signal (or a data representation thereof) for use by the Companion Electronic Device when upscaling the video to restore the original quality of the frame. This could be achieved using hardware or software methods. 7. The techniques above could also be adopted in a fixed setting for example when gaming always use a lower frame rate/resolution or scan frequency as opposed to being dynamically implemented by either Computing Device and or Companion Electronic Device 8. In another embodiment of this invention the physical and or wireless or network interface between the computing device, the companion electronic device (s) or network they are connected to can be switched from one type of interface to another type e.g. Bluetooth to WiFi and or the interface characteristics of any of the connected devices can be adjusted to suit the capabilities of either the computing device(s) or the companion electronic device(s) dependent or resources available to them such as the companion electronic device(s) having a enhanced capability interface. This altering of the interface type or characteristics can be triggered by the interface environment e.g. The presence of interference on a particular type of interface or by the use or running of different applications that require or are more suited to a different type of interface connection. It may also be triggered by other characteristics, statuses or states, such as available system power of either device, thermal status and/or capability of either device, or the presence of additional hardware or interfaces (e.g., one device is compliant with the faster 802.11n standard while the other device is only compliant with the slower 802.11g).
